Some obvious responses occur to a skeptical reader of science:

1. This study has precisely no meaning until it has been replicated, preferably with a larger set of experimental subjects.

2. Science is not one study making ten claims, it is ten studies making one claim. This study falls into the former category.

3. The study describes, it doesn't try to explain. Science requires a testable explanation, one that can be generalized and potentially falsified by independent laboratories. If the study had offered a possible, testable explanation, it would have crossed the threshold of science.

4. It's important to say that psychological studies are virtually never replicated. One reason is that the original studies tend to maker nebulous claims that are difficult to quantify (like this study does). Another is that psychological studies tend not to be accompanied by the original study data, to a greater extent than studies in scientific disciplines. A third reason is that psychological journals tend to reject replication papers, especially those that don't confirm the original study's findings.

~72% of the initial water would freeze as ice.

Phase #1, water cooling and boiling:

mc dT = λv dm

dT = λv/(mc) dm | ∫

Tƒ - T₀ = λv/c ∫ (dm/m)
= λv/c (ln mƒ' - ln m₀) =
= λv/c ln (mƒ'/m₀)

ln (mƒ'/m₀) = c/λv (Tƒ - T₀)

mƒ'/ m₀ = exp[c/λv (Tƒ - T₀)]

mƒ'/m₀ = exp[ 4192J/(kg K) * 1/(2257 * 10^3J/kg) * (-100K)] =
= exp[ -4192/2257 * 10^-3 * 10^2 ] =
= exp[ -4192/2257 * 10^-1 ] ≈
≈ 83%.

Phase #2, water freezing, remaining water still boiling:

mƒ = mƒ' - mv

|Qced| = Qabs

mƒ λc = mv λv

mƒ = λv/λc mv

mƒ = λv/λc (mƒ' - mƒ) = λv/λc mƒ' - λv/λc mƒ

mƒ (1 + λv/λc) = λv/λc mƒ'

mƒ = λc/(λc + λv) * λv/λc mƒ' =
= λv/(λc + λv) mƒ'

mƒ/m₀ = 2257kJ/kg * 1/(2257kJ/kg + 335kJ/kg) * 0.83 ≈
≈ 2257/2592 * 0.83 ≈
≈ 72%
I can help your intuition with the n - 1, I hope. It's true that it's negligible when you're handling cube roots. But when you're cutting down to faces you end up ignoring the entire inside of the cube, so edges can cause problems. Looking at a single face, you have four edges that must be shared, so give away two edges a keep two edges, and you very easily result in a square of n-1 on every face.

This article was published in 2004. It was still causing problems in 2012 [1], when a paper published in the prestigious journal Cell had a few gene names written as dates [2]. Even the GEO [3] had problems with this , according to [1]. The culprit is automatic type conversion, which the user has to understand in order to avoid it. Usually, the way around this problem is to format the columns as text before the data is entered. But it is much harder to work with someone else's munged data or spreadsheet, especially when it is in the form of a .csv file. Even though there is an RFC standard for CSV files, RFC 4180 [4], it is a description of how different editors handle CSV files, and not a prescriptive definition.

Another problem I've seen with dates and Excel is copying date information from one workbook to another. The problem with this is that the workbooks may be using different underlying date systems. Workbooks originating on a Macintosh use the 1904 date system and Windows defaults to the 1900 date system. Copying dates between workbooks can give you shifted dates. http://support.microsoft.com/kb/180162
Just because you think a study seems too small doesn't mean it is scientifically invalid. There are actually statistical tests you can use just for the specific purpose of determining validity. These are much better than some intuitive hunch you might have about the study.

Developer of the kiwiirc.com IRC client here (Unaffiliated with teamrelaychat.nl).
While I agree that there are far better protocols than IRC for todays modern world, IRC still has a long way to go and is currently being extended to push it further in that direction. It still has millions of active users today so it's clear it has done something right.

Inline media, file uploading/sharing, mobile messaging, persistence, log searching, APIs, etc, etc can all be achieved with IRC and is actively being developed with the kiwiirc.com client that this startup is using giving it a great start.

1. Many people like the minimalism of IRC.

2. Being a standard open protocol makes IRC better than any alternative anyway. Can you use Hipchat on a graphing calculator? You can use IRC on one.

I am amazed by the diplomacy shown in the linked article. Nowhere does the article suggest that Excel not be used for such important scientific work, work that has a bearing on human health and well-being.

If the paper had been about drunk driving, or guns in the hands of children, it could be expected to suggest obvious remedial steps along with the data. But as to Excel, it's as though it's the only available tool for data reduction and communication. In fact, it's one of the more expensive of the alternatives, many of which are much better suited to the task being described.
Agree - for me, the persistence is the most important, something which IRC doesn't offer. I'm not always on, and in a business setting it's crucial to be available for messages at all times, even if I'm going to actually read the messages later. I can also find out what the others have been discussing.

Why wouldn't an import tool have an option "make automated conversions" or the ability to _simply_ turn automated conversions off with clear state feedback (eg as a checkable button like for overwrite/insert modes¹).

Surely MS research has shown that this is one of the great pain points with Excel/Word?

Xcelerate is correct. In most studies of any size (in my experience) you start by guessing the effect size that you think you might see. You then try to design your study with a certain power to detect an effect of that size.

You can try to manipulate your power in a variety of ways through the sample selection process (which can ultimately modify your external validity). The major variable that most people manipulate is simply the size of the sample (i.e., the number of people). You need a sample of a large enough size such that you could even hope to detect the effect you expect to see.

Ultimately, one can say, "This study had 80% power to detect an effect size of 30%."

Thanks for pointing out the distinction. You're right that this is what I was going for, but the articles I've seen thus far about the inaccuracies in Excel deal mainly with the poor capabilities of the optimization routines, RNG, and distribution functions. If you're balancing a budget with numbers that involve 2 decimals or taking measures of central tendency on similarly-scaled values, Excel isn't woefully inadequate.

> if you mark a column in an Excel file as text, Excel won't apply magic to that column.

The problem is that the CSV file format has no reliable mechanism to mark a column as text( * ). Known workarounds include inserting a single quote at the beginning of a field, but this single quote may remain in the field forever, polluting the data downstream from the import.

* The obvious approach of enclosing CSV text fields in quotes, and non-text fields without quotes, won't work -- too many Excel versions strip out all the quotes while importing, without considering the implication of their selective application. Also, in many Excel versions "DEC1" is converted into a date whether or not it's quoted.
Just multiplying the P-values from different studies is invalid.

You can intuit this by imagining 10000 studies, each of which had a P-value of 0.99. Seeing 10000 negative studies and no positive studies, you'd be convinced that there was no real effect, intuitively. But multiplying 0.99 10000 times yields a P-value of 2.2 x 10^(-44), a result of impressive significance.

To combine studies, many people use inverse variance weighted meta-analysis, e.g., https://en.wikipedia.org/wiki/Inverse-variance_weighting

Ask HN: Do you think HN should add notifications system?
On one hand, I think it can be quite useful. When I sumbit a comment or a story, the only way for me to know someone replied, is to re-enter HN later. I miss a lot of replies this way. On the other hand, I think it can ruin HN simplicity and "purity". What do you think?
The critical reviews are all irrelevant nit-picking. The vast bulk of Bad Pharma is an attempt to explain to the layperson the implications of a very dry but very important problem. He makes it clear that most of the book consists of illustrative anecdotes.

His core argument is extremely simple: If you conduct any sort of medical research, you have a moral duty to publish all anonymised data associated with that research, promptly and in full. There is absolutely no reason why that should not also be a legal duty.
As usual in threads on topics like this, you can rely on HN participant carbocation's comments for some thoughtful perspective on the original article.

As the submitted article notes, responding to the press releases by the study authors,

"This all raises more questions than it answers. This study was small. The headlines are grandiose. The way people pass moral judgements is not necessarily indicative of their level of existential anxiety."

Indeed. This is an intriguing issue to study, and well worth some further studies by other investigators to see if the results will be replicated in other study populations, but the author of the submitted article was correct to have a headline with an open-ended question rather than a definitive statement about Tylenol. On my part, because I take different over-the-counter pain relief medications when I need any of those, I'm curious if this result would be replicated for aspirin or for ibuprofen. That the pain of stubbing a toe and the pain of rejection in love might have some of the same brain mechanisms is suggested by our use of the word "pain" for both phenomena. But that requires further study. (I'm sure there are many studies already on that issue, but I'm not deeply familiar with the research literature on that topic.) That pain (of either kind) might motivate action and thus dulling pain might reduce motivation for some actions is also plausible, and also has surely been investigated before, but perhaps there are still some very basic facts about that issue yet to be discovered. As so often happens after a new study is published, the most firm conclusion is "further research is needed."

African students invent anti malaria soap
Yup, I'm not suprised. Not a huge market for it but it says on the website its just a 1-person part-time thing. You have to buy the software because theres simply no other (easy) way to get stuff onto a computer that old. The Apple II is a collectors item, and hackers love to tinker with old interesting stuff like that.

I'm not suprised by the price either. The same thing happened with floppy disks. You'd think they'd be really cheap, but in reality they're more expensive than CDs sometimes. The demand is lower, so not as many are made, and they don't get the benefits of scale to cut the price.

Actually that's not true. Generics (at least in Canada but probably true elsewhere as well) only have to give between 85%-120% of the dose of the brand name drug, this is despite having the same official dosage as printed on the label.

I was going to write in disagreement with your point #3, but then I went back and re-read the Atlantic article. In that context, I can see why you would write that. However, I think it needs this context, so to others who were going to knee-jerk react to point #3, re-read the article first.

The study is not impressive. Most studies aren't, and exploratory, early-stage studies rarely can be. It's OK that early studies of a phenomenon are not impressive, but the tests do seem to be extremely narrow. The claims should be equally reserved and narrow. I certainly wouldn't start invoking morality, judgment, or other abstractions of the human psyche (as did the author of this article) from such a small and contrived set of experiments.
This is a terrible article. Yes, the NRA was opposed to extra ill-thought-out mandates on the gunpowder used in ammunition, laws which might make bullets less reliable and would make criminals out of people who make their own ammo. The article writer concedes that it might have been a boneheaded idea, but assumes we could magically fix it by throwing more money and laws at it, like so:

> And if “good science” says existing taggants fall short, then Congress can fund research to develop taggants that work without degrading the quality of the explosive charge in bullets.

So if we had taggants that were proven to work well in this context - which we don't - and if there were a reliable federal registry of where everybody bought their ammunition and ammo and gunpowder and if the bombers had used that exact type of gunpowder...we still wouldn't have found them any faster than we did. But in some purely hypothetical alternate universe where we didn't find them right away and taggants were known to work well in gunpowder intended for bullets and all privacy concerns had been dealt with so the NRA had no reason to oppose it yet did so anyway out of sheer pigheadedness...in that universe, one could perhaps claim the NRA impeded the investigation.

In THIS universe, not so much.

To be honest, I find the UK law to be absolutely stupid in this regard. I needed to buy 10 packs of paracetamol, and at local morrisons I was told I couldn't, maximum was 2 packs(16 tablets each). So I bought two packs, went out of the store, came back in, bought another two, repeated the process 5x and got my ten packs. The whole law is just an annoyance, nothing else. If I wanted to kill myself with paracetamol I could easily get even a 1000 tablets, would just need to drive around a few supermarkets but this law would not stop me from doing it.
