Retirement Calculator Shakedown
Tags: Retirement Planning, Personal Finance, Retirement, Financial Services, User Experience Design

Yup, you probably guessed it, I fell victim to using a shady online retirement calculator; those ‘helpful tools’ provided by your friendly Asset Manager to help you see if you have saved enough for retirement and find out what you need to change. Some call it a ‘veil’ to make you feel scared and appease your fear with sweet financial products (I love a good financial product).

Actually, I’m finding the concept quite useful. Don’t get me wrong; you need trained financial advice and using a reputable CFP is advised. As Hilton Tarrant once tweeted, ‘you wouldn’t not go to the doctor for your physical health, so why not spend money on professional advice for your financial health’, or something like that. I’ve enjoyed them simply because it helps one test various scenarios, at a high-level, and assists to drive the critical thinking.

So I agree that it is a tool that leads to sales, but it’s also a very useful tool which helps people think about retirement and helps them take the steps towards retiring right

So, let me introduce the ‘Battle of the Retirement Calculators’; a shakedown of what’s available on the South African market and how they shape up, based on my evening’s foray into very simple scenario modelling, with a sample of our finest FS institutions’ tools. Take into account that this is the entry point for many people into the retirement planning topic, which makes it important.
Before You Buy Bitcoin…

Bitcoin is a hot topic these days and I see a lot of people willing to put their hard-earned money into this cryptocurrency. Before you jump in, I want you to consider a couple of things. When it comes to picking any new investments, you should always ask yourself a couple of things:

How is it valued What is it worth How will it make money in the future

When I try to value a company, I often look at the company management team, the products they sell, the industries they do business in, and who their competitors are. I look at the potential profit margins they can collect, and whether the company can create value in the future. Looking at these helps me calculate the earnings I should expect in the future from asset value appreciation and dividends (cash income from the stock).

Finding the Intrinsic Value of Bitcoin Is Hard (if not straight up Impossible)

The thing that makes valuing bitcoin difficult is that it is not a productive asset. It doesn’t actually do anything different from one day to the next. One bitcoin today is basically the same bitcoin you will purchase in the future — the only difference is the price you are willing to pay. This leads me to believe that Bitcoin is a commodity, and that its price is entirely judged with supply and demand levels. You see, with a traditional company, you can look at historical revenue figures, future trends and interest rates to calculate the current value of a stock. But with bitcoin, there is absolutely no way of knowing what the supply and demand situation will be in the future, and therefore impossible to value.

More importantly, this leads me to believe that bitcoin is suffering from the Greater Fools Theory — which according to Investopedia.com, “is when you make money by buying assets, whether overvalued or not, by selling them for a profit at a later date because there will always be a greater fool who is willing to pay a higher price.”

This makes Bitcoin a dangerous investment in my honest opinion. There is no basis to where the price can be next. It could end up anywhere.

Should you stay away from it?

Well, not necessarily. For those that are absolutely interested, I can see bitcoin being a small part of their portfolio for diversification/ speculation purposes. Who knows, maybe Bitcoin actually does takeover the world, and could also skyrocket to $50,000. Who knows 🤷🏻‍♂️. However, I don’t think it should be any more than 10% of your portfolio. Because of the nature of this investment, you should be ok with instantly losing 50% of your money — if that happens. If this is your kid’s college tuition, or you decide to borrow money to buy bitcoin, you should stay away from this investment.
This Is How Asian Immigrants Save for Their Kids College Tuition

They Hope for the Best but Prepare for the Worst

My parents were over the moon when my mum finally became pregnant after ten years of trying to have a kid. But, they were also terrified about the challenges involved in raising a child.

They assumed my mum was pregnant with triplets, all of whom would study medicine at university. Some of this may have been the stereotypical Asian parents’ dream to have doctor children. But that wasn’t the only reason.

My parents knew that sending a child to medical school is a costly and prolonged affair. It takes 5–6 years to complete a basic medical degree, then a few more years as a doctor-in-training. This is much longer than the 3–4 years of education that accountants, engineers, or lawyers go through.

Nevertheless, they mentally prepared themselves to have three kids in medical school at the same time and saved accordingly. By making this assumption, they knew they would be prepared for every eventuality.

In a developing country like mine, university places were limited. So, they even prepared to send their kids to a foreign country.

As an international student, I had very few funding options available to me. In the UK, where I graduated, home students were fully subsidised by the taxpayer (things have changed since then). International students had to bear the full cost of their education.

In my day, a home student paid about 15,000 pounds (about $20,000) a year. A 6-year medical course thus would cost an estimated $120,000. Parents with three children would have to shell out $360,000 in fees alone. Add accommodation costs, textbooks, and pocket money — when I was at college, international students were not allowed to work in the UK — and we’re talking maybe $750,000.

Imagine how hard saving $750,000 in a country like Malaysia would be, where the average wage in 1990 was $50 a month.

So, my parents’ financial burden was relieved by having only one child. But, because they were saving for three children, they were absolutely certain about being on track to saving up for that college fund.
IBSIMU on Ubuntu 20.04
By: Andrey Shornikov
Tags: Ibsimu, Physics, Linux

Fortunately, the problem has been around for a while and really smart people made effort to solve it. They created sophisticated codes to numerically model these nonlinear system. Some of them will cost you tens of thousands to license (I am looking at you, former VectorFields/Cobham). Some, such as IBSIMU are totally free and created by people who are skilled in both physics and programming, but despite of being so capable, they are too intimidating for many users to start with.

IBSIMU has astonishing track record of being used in multiple labs and giving reliable results, code is free, there are publications, some community support and even occasional trainings. Yet it remains not as widespread mostly due to very steep learning curve.

Unlike commercial (and many FOSS products) IBSIMU is not a program to run. It is a library to write your own simulation problem in C++ then compile it with IBSIMU under Linux and carry on your optimization studies. IBSIMU itself is distributed not as a package for certain Linux flavor, but rather a source code to be compiled. All of that together means that a simplest model of passing a space charge influenced beam through an einzel lens (that would be the nearest thing to a ‘hello world’) is too intimidating for many to even try.

In this note I share a few steps on how to ease that first step for the current version of IBSIMU and the most popular version of Linux for the next few years - Ubuntu 20.04 LTS.

Let’s start with installing Ubuntu 20.04. If you normally work under windows, you can use Oracle virtual box. For ease of working you may want to tweak things like screen resolution of the guest OS(Ubuntu), or create a shared folder where your host OS can exchange data with Guest OS. We will do these preparations in the next section. If you work on native Ubuntu, skip the next section.

Spacetime, in a nutshell

Spacetime, in a nutshell

What is spacetime? Simply put, is the combination of the three physical dimensions — length, breadth, and width, along with a fourth dimension — time. It is a conceptual model used to explain the effects that occur when travelling at near the speed of light.

A basic understanding of the concept of space-time or figuring out ‘how time (something we can’t really physically conceive) can even be combined with space (something we physically conceive)’ can be achieved through some simple illustrations.

We cannot perceive space-time (4 dimensions) with our senses, but we can try removing some dimensions. Lets begin with 2 dimensional space-time, or 1 physical dimension (length, per say) + time. In the picture below, imagine the point moving with steady speed across the line from the left to the right:

imagine the point moving across the line from left to right

What we observe is a point moving in 1 dimension. But what we really see is a flipbook, with each page being an individual ‘instant’ of a 2-dimensional spacetime. This does sound confusing at first — flipbook?. However, it may become easier to understand with the next image. Let’s add the dimension of time to our 1d movement above:

What?

The image above portrays the 2-dimensional spacetime for the 1-dimensional movement of the point we imagined. But what does it mean? Does it mean anything? You converted a point to a straight line across a box? The picture shows the change in space with time. Imagine a card with a slit in it, place the card on the box above. Now slowly move the slit upwards..

As the slit moves upwards, a point can be seen moving from the left to the right

Our point is seen moving across as we move the slit upwards! What we actually see in the 1-dimensional movement is only an ‘instant’ of the entire spacetime of the movement. This ‘instant’ also changes as time passes. What ‘spacetime’ is, is the entire existence of the point across time. However, we don’t see the dimension of time.

We can also observe this in the 3-dimensional spacetime of 2-dimensional motion. Look at the circle below:

Yes. A circle.

Now imagine the circle slowly contracting and becoming smaller and smaller, until it becomes a point, and then slowly expanding to become a circle again. The spacetime for this 2-dimensional motion would look something like this:

2d motion in 3d spacetime

It may look a bit confusing, but it is the change of the circle with respect to time. The rectangle in between is a card. Imagine the outline of the figure forming on the card wherever it is. Now slowly move the card up the figure. You observe exactly the motion of the circle contracting and expanding.

These illustrations are interesting ways to understand space-time and changes that occur when adding or removing dimensions. As you might have noticed, the spacetime of a 1d motion is 2d, and the spacetime of a 2d motion is 3d. We however, cannot see 4-dimensional spacetime.
What is light in physics?
By: Complex Ob
Tags: Light, Albert Einstein, Waves, Physics, Spectrum

Light is an electromagnetic wave that operates as a result of the vibration of electric and magnetic fields, like other electromagnetic waves. And it is made of photons.

What-is-light-in-physics?

And the thing that makes light different in all these electromagnetic waves is its visibility. We can see only one electromagnetic wave and that is Light Waves. This is due to the fact that the light waves are made up of different-different colors, we cannot see light in combined color form because it is white. But due to changes in wavelength, White Light distributes in different-different colors, and these colors are completely visible to the naked eyes.

The most unusual property of light is its Duality. Till now, there are many people who think that “the light comes from the outer space, it means the vacuum is the medium of light”. But I want to tell them that vacuum is the absence of air, not a medium like air. It means there is something in outer space that propagates light waves through them.

Light Spectrum

When white light passes through a prism, then its component divided into different colors. These divided colors are of 7 types(as seen in the image). They are Violet, Indigo, Blue, Green, Yellow, Orange, and Red. These colors are called bends of colors and this bend called Spectrum of Light.

Dual Properties of Light

1. Wave Nature of Light

In the year 1864, When James Clerk Maxwell published his “Dynamical Theory of the Electromagnetic Field”, then we came to know that “Light shows Interference which is the property of a wave”. In this way, people and scientists believed that light is a wave for another 41 years(1864–1905).

2. Particle Nature of Light

In the year 1905, When Albert Einstein(one of my favorite physicists) published his concept of the Photoelectric Effect, then we came to know that “not only wave nature, the light also shows particle nature”. In this way, after 1905 everyone believed light has Dual Nature(Wave as well as Particle).

The Things You Should Know About Light:-

The rest mass of light(photon) is zero and its relativistic mass is undefined.

The light and all other electromagnetic waves in a vacuum or air medium(this is not a real medium of waves) are 299,792,458 meters per second(approximately 300,000 km/s).

Speed of Light is called Speed Limit of the Entire Universe according to the Special Theory of Relativity.

The frequency range of visible light is 4 × 1014 to 8 × 1014 Hz

The wavelength range of visible light is 380 to 740 nanometers.

Directly and indirectly, all energies on earth come from the sun in the form of light waves.

All waves include Light have momentum without rest mass, they carry the energy and always in motion.

This is enough for this question

What is ether in physics?
By: Complex Ob
Tags: Light, Waves, Physics, Ether, Médium

The Luminiferous Ether:-

In the 19th century, when people came to know the light is a wave then Scientists started raising the question that if the light is a wave, then in which medium is it traveling like other waves?

what-is-ether-in-physics

Nothing was known about this medium, due to which it was named as the Luminiferous Ether. Before the end of the 19th century, everyone believed that light rays travel in this hypothetical medium called Luminiferous Ether.

But two American physicists Albert Michelson and Edward Morley trying to prove the existence of this hypothetical medium in the year 1887. But the result was surprising that light does not need any medium like Ether for traveling in space.

That means, in our universe, there is no such medium as ether.

Tags: Sound, Light, Physics, String, Ｍedium

Warning: Only read if you are a science student

Medium is a special type of group of substances, with the help of this a wave or particle travel from one place to another. Nothing can go from place to place without a medium even us.

What-is-medium-in-physics

For example:-

String Waves

String Waves used string as a medium to travel. For example, we tie a string to two sides of an object. Then as soon as the string is moved from one side, the wave generated in the string on that side reaches the other side through the medium od string

Types of Medium

There are two types of medium in physics they are:-

Denser Medium Rarer Medium

Denser Medium:-

The medium in which particles or molecules are close to each other is called a denser medium in physics. For example, water, honey, solid objects, etc.

Rarer Medium:-

The medium in which particles and molecules are far away from each other is called Rarer medium in physics. For example air, etc

Did you know

Sound Waves are faster in water as compared to air.

PHYSICS — Kinematic with JavaScript Part 1
By: Muhammet Kandemir
Tags: Kinematics, Math, Physics, JavaScript

Everyone asks why we’re learning derivative or integral or anything else which seems like an unnecessary thing. It is not unusual because we don’t know how to use it. Let me give you some examples to understand;

Each game engine must calculate position of an object by using 3D formulas to put it on a correct location on the screen. But how does it happen? There is just one answer that with science(MATH, PHYSICS and etc). To make it clear, can you know what an object’s position is at after another object hits it with 30 km/h velocity? It is general thing mostly known like in games(GTA, PUBG and so on). You have to use momentum to solve this problem. As we’ve seen, science helps to know what is going to happen in the future although not exactly.

Now, we can try it with an example which is coded by JavaScript. I had prepared an example and shared via GitHub before I wrote this story. There are just kinematic formulas to explain how to work Projectile Motion with an object while is being applied another forces(Friction and gravity). Just check it out to recognize why we need to study PHYSICS and MATH. You will see there some formulas in source code which is coming from Kinematic Formulas and a little bit MATH equation. You can also change the values to see what will happen for another scenarios.

Link : https://muhammet-kandemir-95.github.io/PHYSICS-Projectile-Motion/

Sum of all, you can improve this codes to do better like a game. Actually, all game engines already present us short methods to solve kind of this problems. However, it is better to know how it works than not to know.

Our curiosity to know about the composition of things around us, is not recent. As old as two and half thousand years ago, natural philosophers like Kanada and Democritus suggested that the Universe might consist of atoms. Their theories were mainly philosophical models and thought experiments, because of lack of advanced mathematics or experimental setup at that time. Despite the facts, it feels incredible that their thoughts somehow sparked the formal inquiry into matter and energy. We have kept asking ourselves the question of composition of matter in the Universe. Today we know much more about atoms, electrons, energy, and the their roles in the observable universe. Still the answer to that question is equally fascinating as it was in the antiquity. It takes us on a journey from the everyday objects (cats, cars and trees) to that unseen or un-seeable (if that’s a word) world scientists have been talking about for quite some time. So, where do we start? In his wildly famous science book Cosmos, Carl Sagan writes,

If you wish to make an apple pie from scratch, you must first invent the Universe.

— Carl Sagan

The universe is a strange place where the natural laws appear to be different depending on the size of the entities. Electrons with their bizarre uncertain probabilistic nature look very different than a normal tennis ball bouncing on the grass, although the latter one is made up of the prior one. Principally, you can zoom into the tennis ball and observe the weird phenomena of electrons. The laws are same (symmetrical) everywhere you go (see Gauge theory), it’s just the appearance of them changes.

Depending on the perspective, we are either trapped, or safely cushioned between the bizarre worlds — one with electrons, quarks, photons, and the other one with big stars, galaxies and super-massive blackholes.

It’s difficult, rather impossible for our minds which themselves are products of millions of years of evolution and cultural upbringings, to understand something that’s out of scale by such a large extent on both the ends. Understanding them takes special efforts on a personal level and a deep commitment to follow through several levels of abstraction. Language is often inadequate when we describe these concepts. After all, language as a tool to query and explain nature is only a recent invention of mankind!
What existed before the Big Bang?
By: Sraboni Modak
Tags: Space, Universe, Big Bang, Physics, Science

How did our universe originate?

In some of the dark situations that come up in our life everyone is questioning how this universe came to be? Everyone knows that science’s answer to the question of how the universe came to be is the Big Bang. This Big Bang theory, however, is in a way based on Einstein’s ‘General theory of relativity’. But before that we need to talk a little bit about a mistake made by Einstein in the days when there was no Big Bang Theory.

What this means is that when the field equations proposed by Einstein were applied to this universe?

Einstein observed that the universe would expand or contract. But in the old days it was believed that the universe was permanent without moving so Einstein thought that even these field equations, when applied to the universe, should be constant. To this end he introduced a new cosmological constant in his equations. The universe became balanced when used but later Edwin Hubble’s research found that the universe expands, so Einstein also removed this cosmological constant from his equations. That is, Einstein’s equations predicted that the universe would expand.

What come before the singularity?

So the question of what happened before the big bang is also wrong because time starts with the big bang and there is no time before the big bang so the word event does not even make sense.

The flow of time is just an illusion | Brian Greene
By: Detective Red
Tags: Time, Mystery, Physics, Illusion, Science

“Once upon a time” is ………

Many good stories begin with this magical phrase, but have you ever thought that “what is the story of time?” Does time exist? We always say time can be spent, time is money, we waste time, we are trying to save time, but what do we really know about the time? Is time an illusion? According to physicist Brian Greene, “all the time exist at once in spacetime”

Well, time seems like an unchangeable flow like a river from one moment to the next and we always see the flow of time in one direction only towards the future. But this is not true. From the discoveries of the last century, we find that what we think about time is nothing more than an illusion. Unlike our everyday experiences, time does not flow to anyone at all.

Our past may not be gone and our future may already exist. We know that the speed of time can be fast or slow and all the events that seem to be appearing in only one direction are not true. They can also appear in the past. But how can this be? How can we be so wrong despite being so familiar with time? If time is not what we think it is, then what is time really? What is the beginning of time? Where does it come from?

A Visual Guide to the Uncertainty Principle
By: Colton Kawamura
Tags: Computer Science, Physics, Education, Mathematics, Science

The Heisenberg uncertainly principle captures the experimental and theoretical phenomena that you can’t ever really have full information about both a particle’s position and momentum at the same time. To increase certainty in one, you must give up certainty in the other. Quantitatively, it is described as follows,

A dive into Fourier analysis can explain this much more analytically, but for now, let’s stick to these animations.

Where is the Wave and What’s its Momentum?

In the image below: ask yourself Where is the wave?

You can probably tell with some certainty that the wave is where that hump moving to the right is. Now ask yourself this question What is the wavelength? This question is a little hard to answer since the wavelength is the distance between repeating parts of a wave. But what if we had a longer pulse of a wave?

Here, the wavelength is much easier to determine since the wave repeats itself. But what happened to the position of the wave? It’s smeared across the length of the pulse — it’s more uncertain. We just traded certainty of the wavelength for the uncertainty of its position.

Momentum Links to Other Information

So what does this have to do with momentum? On quantum scales, particle’s wave-like behavior dominates. Physicist de Broglie linked particle and wave characteristics together with the constant, called Plank’s constant:

The Big Picture

What does this mean for our everyday lives? One of the many examples includes solid-state hard drives, which takes advantage of the phenomena the uncertainty principle models. A fluctuating position of a particle can enable it to move through a barrier that it classically couldn’t. This allows electrons to be stored in space without the use of a capacitor, which allows for the non-volatile flash memory we have in most modern electronics.

All images were produced by me and are free to use however you’d like, but some credit would be nice. Code is found here.
Speed of Light isn’t c. Or is it?
By: Rak Laptudirm
Tags: Physics, General Relativity, Proof, Speed Of Light

There are numerous things in physics which we are not certain about. But the speed of light? We are so certain about it that we even defined the length of 1 meter using it. It is the distance traveled by light in 1/299792458th of a second in a vacuum.

As discussed in the above video by Veritasium, no one has ever measured the 1-way speed of light. We have always calculated the two-way speed. Therefore, if light travels at different speeds in different directions, it would imply that our value of c is incorrect.

Due to the restraints provided by general relativity, it is impossible to calculate the one-way speed of lights, the problem being syncing clocks.

The problem being interesting, I have thought about it. I am sure that we have the correct value of c. I have 2 arguments for it:

1. Stopped clocks:

One of the problems discussed in the video is the problem of syncing clocks. Before going forward with my argument, we need to grasp the meaning of time.

Time is the measure of the rate of change in a single inertial frame of reference.

According to the theory of relativity, moving frames have a different measure of time from stationary frames. That makes syncing the clocks a problem(Video for details).

But if we stop both the clocks, frozen at 00:00, moving them won't affect the sync of the clocks because nothing is changing. When we have them in position, the clocks would still be synced.

We could have a button in the middle, pressing which would start both the clocks at the same time, syncing the clocks.

I am not an expert in General Relativity, so I am not sure it works. However, I am sure of the next one.

2. Size of the Universe:

Our Universe is the distance from which light has traveled to us since The Big Bang, roughly 13.7 billion years ago, or, in other words, everything we can see from the earth belongs to our universe.

If the speed of light is c, then our universe is a perfect circle centered on us with a radius of 13.7 billion years around us. If it is not, then we are not the center, but towards the edge:

We can measure the distance between us and heavenly bodies accurately using redshift and parallax. If we can find the furthest objects we can look at from different directions, we can compare the distances. If they are roughly the same, light has traveled at the same speed towards us.

If there was such a phenomenon, I think it would have amazed physicists and we would come to know of it, and since I don't have such information, I assume we are in the center of our universe, and the speed of light is c.

Conclusion:

Since we have NASA Deep field images (images of celestial bodies more than 13 billion light-years away) from various directions, I, using my second argument, can prove c at a precision of ±3349345 m/s, as light has been found in almost every direction from a distance of 13.3 lightyears. It is not possible for me to prove this at a higher precision, as I don't have the equipment to take Deep field images.

Introduction: Inner battles and timewaves

By Dov Sabastien

Christmas

What a strange main title. There is a good reason as it's named after…Nevermind. Let me tell you a story. Soon a book will be published that dives into the details, but for now, this should do.

My story not only moves through time but is influenced by the physics of time itself. It draws upon events from the past and what’s to come in the future. It's a story of a classic battle fought by powerful adversaries. It’s also a battle that happens inside us as we combat our demons and fears, hopes and aspirations, and our innate drive to protect those who we love and protect. Over the next months, years and centuries (both past and future), I will share as much as I can of the story, not conventionally told.

Today I am in Boston, Massachusetts, and I live across the river from MIT in the Back Bay community. I understand it's an exclusive and expensive part of Boston to live in. I wouldn't know specifically as I have only recently arrived here and I am living here with my very good friend, Cara.

We live together and are working on some interesting theoretical physics. We have discovered that time can be hacked but I am getting way ahead of myself. Suffice to say it's important to close that loophole. That we reinstate the quantum time variable within the closed timeline curves. I am not sure how we can fix the time-wave disturbances or even reverse the damages done this far, but we must try.

Speaking of damage I would like to say immediately, regarding the power outages after the accident at MIT, I am so sorry to those who suffered an injury or loss. This is partly why I am writing this blog. As a medium for healing and to be transparent. Though I can’t give away ‘the plot’ so to speak, at least not yet. So please enjoy as I add to this whenever I can get around to it.

I would add “A brief History of Nearly Everything” by Bill Bryson. His humorous take on science, astronomy, geology, physics, evolution and all major advances makes easy reading without devolving into science for science’s sake. Bryson explains just how miraculous it is that we got here and what a tiny flyspeck our existence is within the universe. It’s oddly reassuring to learn how borderline crazy geniuses such as Isaac Newton were.

Do Atoms Ever Touch?
By: Colton Kawamura
Tags: Math, Physics, Education, Quantum Computing, Science

Overall, yes. But there’s more to this question than a simple answer. So let’s break down atoms into two parts and answer this question separately.

Do the Nuclei of Atoms Ever Touch? Yes.

The nuclei in atoms of our everyday lives usually don’t touch each other. Even the nuclei under a 20-story building aren’t in contact. Outside of our daily experiences, nuclei definitely can touch. In particle colliders, physicists throw atoms at each other to make their nuclei smash together. In space, immense forces cause atoms to squeeze together until their cores touch. But enough about the nuclei, what about the electrons in atoms — do they ever touch?

Do the Electrons of Atoms Ever Touch? No.

Here’s the thing: we have to consider the quantum characteristics of electrons. This means that they act as both waves and particles. Wave-like electrons are spread out over space and oscillate over time, so their location is often described by an electron cloud. This electron cloud represents the density of probability of finding an electron if you were to measure its position. It’s not that the electron is buzzing around within this cloud, it’s actually smeared out in space.

Quantum particles don’t have a defined position, but exist as cloud of probability of being found in a location.

These electron clouds have seven different characteristics that define how they can exist — we call these types of particles fermions. Think of these characteristics as seven digits to their “address” in the universe. Three of these digits make up where it physically resides in 3-D position space. The next three describe the electron cloud’s momentum in each spatial dimension. The last component represents the electron cloud’s spin. No two fermions can exist with the same unique seven-term address.

This property can lead to some pretty interesting situations. For example, we can have two identical electron clouds but differ only in their spin component. This means they can exist at the same point in the universe as long as they have different spin. This property is analogous to how ghosts in movies can pass through walls. These ghosts have a similar spatial location in our world, but they exist in some after-life dimension. This allows them to occupy the same space as physical objects and thus pass through walls, etc.

If the wall was made of only spin-up fermions, a spin-down fermion could pass right through just like this ghost

This, of course, is made up movie stuff, but fermions are not. So even though electrons can exist in the same physical location in space, they can’t have the same seven digit address. Therefore, they never touch. The philosophical reason why fermions exhibit this property is still an ongoing challenge even though it is perfectly predicated and described by mathematics.

Youtube Physics video by Veritaslum

Nobody changes their minds about anything, ever.

This is a simple experiment about people’s beliefs about falling balls. Nobody is saying anything physicsy about “freefall”, “under the earth’s gravitational field”. The experimenter holds up two identically sized balls, one is a relatively light red basket ball and the other is a heavier black medicine ball. All he does is ask people, if the two balls are dropped simultaneously from the same height, which one will hit the ground first.

What do you think will happen?

Universally, everybody is very certain the black one will hit first. In some cases, even after the demonstrator tries to instill some doubt in their thinking, they go back, even stronger, to their original “black will hit first” belief.

Now watch the video, but stop after the experiments have been performed, at 1:45.

What do you think happened?

Again, everybody on the video sees that the black one landed first, justifying their original belief. Is this confirmation bias? I think this is self-justification “See, I was right!” bias. They aren’t even crowing about it. They are like, “Of course I was right, no biggie.”

Now continue the video, they watch the experiment in slo-mo. Guess what happens. Now the subjects do concur, with the evidence before their eyes, which seems undeniable, that “both land simultaneously”.

See how hard it is to convince somebody even of what we take to be objective reality? And this is just Physics — it is not as if it is about your core beliefs about human beings, your morals, your racism … nothing. Most people hate Physics and so you would think they don’t care enough about it to be right (or wrong).

Is that the end of it? Nooo! Because now what happens is that people start coming up with squishy stuff, to slime their way out of having to admit they were wrong and thus having to give up their beliefs and possibly change their minds. One person argues that “the balls didn’t fall far enough … to reach their maximum speed”. There is so much wrong with this I won’t even start, but I hope my main point has been made:

People will deny the evidence before their eyes in order to hold on to their beliefs. If reality -the evidence- is too overwhelming to easily deny, they will come up with the most hare-brained of ideas, crackpot thinking, the equivalent of “conspiracy notions”, in order to maintain their grip on their beliefs.

So now, imagine trying to convince someone that vaccines cause autism or that Trump won the election but it was stolen due to fraud or that the Earth is flat or that the government is run by a bunch of Russia loving pedophiles. Not going to happen.

Nobody changes their minds about anything, ever.

Except, mostly, hard scientists. Yeah, I know this is going to piss people off. But in terms of openness to change and the inverse timescales on which they are willing to do so, probably: Mathematicians > Physicists > Chemists > Life Scientists … > the heavily politicized and finally, religious people.
What is Gravity?!? Pt. 1.
By: Edwin Sanish
Tags: What Is Gravity, Physics

A bit of context: I am a 14-year-old trying to find out how some of the things around me in this world works. I have no experience in this field other than high school physics. This is a series of blog posts where I write about all the topics that I come across while trying to figure out how gravity works.

I’ve always been told that gravity is a force by which the earth pulls objects toward its surface. I was never satisfied with this definition for the following reasons:

For the past 9 years, all I’ve ever been told about gravity in school is this definition, calculations of gravitational force, and that an apple fell on Sir Isaac Newton’s head.

The textbooks never had any information on how the force works or why this force works.

So I decided that I was going to find out what gravity is and how it works.

This is the 1st Part of the Topic “What is Gravity?” where I talk about how gravity works in space between objects in space

The first thing I found out is that this was already done. Gravity had already been figured out by Albert Einstein.

So here’s what I found out after doing some research :

We, humans, are very small creatures on this planet. The only dimensions we can access are Length, Depth, and Height but it turns out that there exists a fourth dimension in the universe.

This dimension is called Spacetime. Einstein found out that the two closely related parts of reality could be joined if the speed of light was constant. This is a vast topic that I am researching currently. I will be writing on all the topics related to spacetime later in the blog.

For now, in this blog post, I am going to try and help you to visualize Gravity that is experienced by objects in space.

Space-time is like a huge trampoline in space on which all of the objects in space move around.

So on this trampoline are objects with different masses that create curves on it. Like in the image above.

Now when there are many objects on this trampoline, like in space (due to Entropy), many curves are formed on the trampoline (Spacetime).

This results in the formation of very steep slopes around the bodies having large masses. So the bodies with less mass, move along the slope towards the heavier body. Hopefully, this image could help you visualize this concept

.

This is how bodies of greater mass in space attract bodies of lesser mass.

Hope this helped!

Leibniz crossed the realm between darkness and certainty. Now humanity is crossing the realm between certainty and uncertainty. Inside a black hole is beyond our understanding. We’re still finding acceptable interpretation of wave function. Singularity is a reality. Our world is fundamentally uncertain by quantum mechanics. The perfect mechanical world ticking flawlessly and eternally is gone. Einstein made the wrong assumption of a static universe. Still Einstein is great, Leibniz is great too.

Physicists will never truly understand consciousness until they STOP looking for “physical" causes…

Tags: Physics, Quantum Physics, Consciousness, Science, Mindfulness

Physicists will never truly understand consciousness until they STOP looking for “physical" causes for it. Consciousness is the ULTIMATE causing factor, meaning all else stems from IT, not the other way around. Even some of their own experiments (especially those of quantum physics) allude to this, like the double split experiment for example, but physicists continue to ignore such things. What’s plain as day seems to get ignored the most within the so called western “scientific community.”
