content: hey guys first time long time here, ive been getting really into frequencies lately and I was wondering has there been a video on it yet? I havent seen one done by eevblog, and i couldnt find it on the forum. If its not on here can dave make one pleaseeeeeeee?also is there any cool videos or books on the magic of frequencies? I know the subject matter is large but what I like to get into is how frequencies can grow things, or can make certain things do weird things, stuff like that. Thanks have a good weekend!

Just to chat about them, like just start talking about them. I dont know much about them and I would like to learn more thats why I cannot be super specific about it.

Ive tried to find some videos and stuff but I cant really find anything that great. There is a scientist that I come across a lot when I look up frequencies that has a lot of cool research name Andrija Puharich. I dont know if you guys heard of him. His stuff is pretty cool. Im looking for things in his subject matter.

content: Quote from: texwitheffects on August 15, 2015, 08:10:04 amOK, I'll play."Frequency" basically means how many times something happens during a certain time interval. If we consider the clock second to be the time interval to define a frequency, the we are talking about "events per second". If the "event" happens to be a repeating signal of some kind, like a cycle around some parameter space, then we are talking about "Cycles per second". Now the people who assign names to things decided to name the unit "cycles per second" after a fellow named Hertz. So now we can talk about "frequencies" in terms of Hertz, or Hz for short. Whenever you see "Hz" describing a frequency, you can mentally substitute "cycles per second". And we can use prefixes to talk about very rapid frequencies, like KiloHz or kHz (thousands of cycles per second), MegaHertz or MHz (millions of cycles per second) and so on.Now there are many different things that can vibrate. Sound, for example, is a vibration in air, a string of compressions and rarefactions of air pressure that cycle between about 20 Hz and 20 kHz. Radio waves are electromagnetic vibrations that can run from very slow (even below one Hz) to very fast, like several GigaHz for your cellphone for example. Light is actually also a vibrating EM phenomenon with frequencies so great that it is easier to talk about wavelength instead. The wavelength of a vibration is the inverse of the frequency, scaled by the speed of propagation of the vibration. For example Red light of about 620 nanometers wavelength has a frequency of about 400 TeraHz (trillions of cycles per second). For sound waves, a frequency of 440Hz corresponds to a wavelength of 78 centimeters (in air at 20 degrees C).So the word "frequencies" is just a name for the rate at which various vibrations of various things occur. So, taking sound for an example system of frequencies of vibrations of air, we can see that certain shapes and sizes of things want naturally to vibrate at certain frequencies. Like a guitar string: the more tension it has, or the shorter it is, the higher the frequency at which it vibrates. A similar thing happens for electromagnetic frequencies.Is that good for a start?

content: You'll enjoy the camerawork in this one.In the film, which I do recommend, Captain Patrick Zevo (played by LL Cool J) and his security detail discover the photocopying room. Obviously, this is a blatant security risk. As Captain Zevo states in serious tone "Where there is copying, that means there is more than one !!!"Copying and frequency have similarities and differences., There are more than one, like trolls, who find new ways to waste time, there are more ways to do that than just one. The game of pretend to be dumb is a first choice because trolls have great experience in that department, it's so close to home. But as it's easily spotted, it's often not the best choice. So there is more than one, like copies, boobs and frequencies.

Ive been meaning to watch this movie for a while but it just hasnt been around me to remember it. I really love movies that have hidden messages in them that motivate me or keep me thinking about what is reality. Another great movie to watch is actually called "frequencies" lol on netflix. Its a pseudoscience movie but its really fun to watch stuff like that. Another great movie is "the thirteenth floor".There is some talk going on right now about how china was able to make a holographic city appear and look real. Whether thats real or not the idea of being able to make a whole reality from thin air by different light refractions is really fascinating. There is even technology now where they have been able to make a hologram that you can touch and manipulate. I really wish I could learn more about that. I wonder if there is somewhere where there are normal everyday electronic engineers experimenting with that. I would loveeee to hang out there and explore those possibilities.

In the UK, the age at which you are most likely to be a homicide victim in under 1 years old (not 16-24 which would be most people's guess)At least one of those statements is true.

content: On the high end, one frequency I really like is 740THz. It's extra useful when giving presentations and is sure to attract attention. 564THz was also nice until it became too common. 461THz was once the standard for presentations and has a secondary use streaming HD digital audio. A little further down (but still in the few hundreds of THz) are the frequencies often used to stream digital data over long distances. There's also some research about using frequencies around 1PHz for data storage.On the low end, there's something unusual about 413nHz. While it is often said to be a rather troublesome frequency, it has a strange correlation with the more attractive engineers.And in the middle are all the frequencies engineers typically work with, including the common crystal frequencies:https://en.wikipedia.org/wiki/Crystal_oscillator_frequencies

content: The original electrification of the Swiss railways was at 16-2/3 Hz.However, the Pennsylvania RR in the US used 25 Hz.This is a compromise between the weight of variable-ratio transformers (on board the locomotive) and the use of DC motors on AC.Of course, 16-2/3 Hz was derived from commercial 50 Hz power, presumably through rotary converters at the substation.

content: Quote from: texwitheffects on August 16, 2015, 10:22:40 pmLol, I think what you've failed to understand is the different types of waves which propagate through air.There's sound which consists of mechanical pressure waves and needs something (be it gas, liquid or solid) to be transmitted. Then there's electromagnetic radiation which consists of alternating magnetic and electric fields and can pass through a vacuum.When electrons move around electromagnetic radiation is generated. The higher the frequency, the higher the energy. The electromagnetic radiation generated by the electrons moving back and fourth at the extremely low frequency of 60Hz does not have enough energy to affect your brain - the person who said that was joking with you.https://en.wikipedia.org/wiki/Electromagnetic_radiationThe only way mains power can affect your brain is when an electrical current is passed directly through the brain but you need to be in electrical contact with the conductors for that to happen. Simply standing next to a mains socket or transformer will not induce a high enough current in your body to do anything.

content: I read this: "If an AC current is fed through a piece of wire, the electromagnetic field that is produced is constantly growing and shrinking due to the constantly changing current in the wire. This growing and shrinking magnetic field can induce electrical current in another wire that is held close to the first wire. The current in the second wire will also be AC and in fact will look very similar to the current flowing in the first wire."Obviously we have a current in our bodies, and when someone comes into our area with a pissed off energy we become pissed off. Or when someone is super happy then we become happy. Their frequency changes our frequency. Thats why im starting to think that maybe this 60hz could alter our attitude.

Try applying some common sense to some of your questions.Certainly there are some people who claim that living near power lines or a broadcast transmitter (or even their cell phone next to their ear) somehow "affects" them. And yet there are 10s of millions (or 100s of millions) of people who live/work/play in close proximity to these "sources" without any apparent effect. The effect appears to be almost completely psychological. If you can convince someone that some sort of invisible "frequency" or "waves" or "rays" or whatever is affecting them, they will start to show symptoms, even in the absence of any actual "frequency" or "waves" or "rays" or whatever.

content: Quote from: Richard Crowley on August 17, 2015, 12:01:14 amPeople are hard-wired to find 'meaning' in things - it is hard to comprehend how random chance can be at play. Be it vaccines causing autism in their children, or the will of the gods, or bad luck coming in threes. Likewise it is possible for beliefs to cause symptoms - who hasn't bitten into a bad apple, only to feel sick even though no harm has been done?If somebody lives next to a chemical plant and have eczema then it is natural to connect the dots, just as it is natural to assign it to changing soap powders. Don't get me started on how many bottles of shampoo a flatmate had because if she used the same one for too long it made her hair break...And even EEVblog isn't immune to it - all the time we hear 'lore' assigning symptoms to faults that don't exist... be it about inexpensive Arduino clones from China, counterfeit FTDI parts or the quality / accuracy of low-end test equipment (or even high end equipment). And things like the endless digital vs analogue scope debate.But back to topic - nobody could argue that a house isn't filled with EM waves emanating from all the electrical stuff in it. Does it have a biological effect? Not a significant one, unless you put your head in a microwave and switch it on, put a finger in a mains socket, or sit too close to the heater. If it was significant we would have data to back it up.And I guess data would look a bit like this....

Exactly what kind of effect do you think those frequencies should have on us?You can pick any frequency, audible, visible, or undetectable and likely convince someone it is "affecting them". This is not a physical or scientific effect. It is a psychological trick.

content: Quote from: texwitheffects on August 17, 2015, 01:09:33 amI did Google Vortex Based Math, and applied my rule of thumb - if it doesn't have a Wikipedia page, then it is most probably not worth it ;-)However, I too have only just started really appreciated that pretty much anything can be described as a lot of simple harmonic motion (sine waves) of different frequencies and phases, all combining together. But let me digress...I am also well aware that my experience is most likely not the true nature of something. Take white light - is white light being a continuous spectrum of all visible light frequencies (sunlight being an ok approximation of white light), or is it the right mix of red green and blue (like the white light from my LCD screen is)? Only putting the light through a prism reveals what the white light really is.If I spend a second wiring a switch, wire and an AA battery, and close the switch for 1 second, you get a 1.5 volt pulse can be described in the frequency domain as a continuous series of infinite sine waves all added together. How can it be true that these component signals extend before and after the circuit was made? Is it just a trick of the analysis in the frequency domain? Or is that its true nature, that my actions caused a whole lot of different waves converged exactly as needed to make that pulse occur?If I had the time to think about it I too would struggle with things that I experience that are wrong:- There is no such things as pure white light- Things can not keep keep getting colder- Things can not keep going faster- Conservation of matter is a lie- Solid objects are not mostly empty space- Unless I measured it, I would say pebble falls slower than a cannon ball - brain seems to get confused between speed and momentum- light is not instantaneous- PCB traces can actually be active componentsI can also see how at one time the world was believed to be flat - if it made no impact on your day-to-day life why would you think anything different?There is enough mystery in the world to ponder without reaching for pseudo-science. It is just that real science is actually harder to understand as the world doesn't truly work as your senses tells you.

content: Quote from: Richard Crowley on August 17, 2015, 02:20:15 amI agree it is sort of a trick, but if I hold a white bit of paper beside my screen, I can't tell you which is the "truer" white. They are both white - but I am sure one is just the correct mix of R+G+B to look white, where as the other is an object that is not particularly good at absorbing the visible light that lands on it.Sometimes without the colour cues it can alter your other senses - have you ever found that you can't tell different flavours of lollies apart in a movie theatre, because you can't see what colour they are. It has happened to me, yet they packet says they have different flavours.... apart from the green ones - they always taste like toilet cleaner to me!.You will also never see strong purples on TV, as they can't be expressed in the RGB system and end up looking grey. And unlike a blue/red colour, you can never directly experience a blue/yellow mix (and no, that isn't green!). but you can trick your brain into letting you experience it.

content: Quote from: hamster_nz on August 17, 2015, 03:08:57 amThe "color gamut" of RGB displays is commonly shown within a triangle on the CIE 1931 Chromaticity Diagram. This example shows the disparity between human perception (the very outside of the color area) vs. the NTSC color definition (the larger triangle) vs the color gamut of a typical LCD display. Note how much of the purple area is truncated.QuoteWell, the color wheel shows that the combination of blue and yellow actually is green....

content: Quote from: Richard Crowley on August 17, 2015, 03:34:18 amI don't know who made that colour wheel, but it seems to be shifted around somewhat. Blue = #0000ff, Yellow = #ffff00. Add them together, you get pure white: #ffffff. Your colour wheel may be based on paints, which are a weird mishmash of additive and subtractive colours.

content: Quote from: Richard Crowley on August 17, 2015, 03:34:18 amThat's for subtractive color (paints and pigments). And it's an oversimplification. The true primary colors of subtractive color are not red, yellow, and blue, but rather magenta (red light + blue light), yellow (red light + green light), and cyan (green light + blue light).Yes, if you mix yellow and cyan paint, you're left with something that absorbs red and blue light and reflects green - hence green.We were all told "red, yellow, and blue" in our earliest school years because it was simpler (the "lying to children" principle), and because the small box of Crayons doesn't include "cyan" or "magenta".Also, you cannot make true violet by mixing red and blue. That gives magenta, a color that decidedly looks as if it has red in it. But true violet doesn't look like that. It does not tickle our "green" or "red" cones at all. It looks more like "bluer than blue" than any sort of purple or magenta. And you will never see it from a TV or computer screen, not at least with the primary colors they're using now.

content: Talking of frequencies, in one of Steven Hawkings books he talks about frequency and wavelengths and mentions that it is possible to have frequencies so low that the wavelength is as long as the universe is across.This got me thinking that if you detected such an electromagnetic wave how would you know that it was AC as it would be so slow that in a human lifetime it would look like DC.

content: Quote from: tggzzz on August 17, 2015, 07:40:08 amSee above where I said "if not monochromatic yellow"? I suppose I should have qualified "monochromatic" with "(or nearly so)".Another good source of nearly monochromatic yellow is your typical yellow LED.And re "not one green and one blue line", I'm quite sure you meant "not one green and one red line".(Verb. Sap.: When you undertake to sternly correct others, you really need to read what they write carefully, be willing to give them alittlebenefit of the doubt e.g. "(or nearly so)", and also not make mistakes of your own...)In any case, I'm sure we're agreed that yellow is never a mix of green and blue lightQuoteSure. But so can red light + green light, thereby creating the perception of yellow. Or brown, which is usually a low-lightness, low-saturation yellow.

The reason for this is because the human body is a poor conductor of electricity so to induce a significant current, the magnetic field would have to be much stronger than that produced by a power line or mains transformer.https://en.wikipedia.org/wiki/Near_and_far_fieldYou're also talking about the near field region which is not electromagnetic radiation.

This statement "their frequency changes our frequency" is as nonsensical as "their distance changes our distance", or "their color changes our color". It is meaningless, and, no offense, it makes you sound like an idiot."Frequency" is not some independent tangible thing that you can go out and poke or measure. Frequency is a property ofSOMETHING. Saying "frequency" without specifying the frequencyOF WHATis meaningless. Frequency is simply the rate at which something happens. A person doesn't have a frequency. A person might do things with a certain frequency, maybe they go to the bathroom every 2 hours, or their heart beats 80 times a minute. Those are frequencies. You're just talking about moods and then calling them frequencies for some reason...Quote from: texwitheffects on August 17, 2015, 02:25:08 amThat's a physical problem in their brain. Their senses are wired incorrectly, the signals from the eyes for some reason are being routed to the area of the brain that interprets sound. They're not actually "hearing colors", because color has no sound. Their brain is mis-wired, which is causing their senses to get confused.
