Anything that increases the flow is therefore treated as a positive, even if it is clearly a negative for the society. True. GDP doesn't measure, nor does anyone claim it measures, societal well-being. So, is GDP a flawed measure of progress? It isn't a flawed measure of progress because it isn't a measure of progress. It is a measure of economic ...

This addresses the second claim. I doubt anyone will read it but it's fun to bring up the old neurobiology knowledge every once in a while In terms of neurobiology, you have 4 types of photoreceptive neurons in your eye. One is the rod, which is sensitive to green but creates a black/white percept (for "scotopic" or night-adjusted vision) and the other 3 ...

Does using a computer affect your eyesight?

I've heard it said very often: Using a computer/smartphone can make you nearsighted. Is it true? Is there good research on the topic?

This phenomenon is called olfactory adaptation. It basically means that your nose gets adapted to the smell so that you feel like it's not even there. For instance, when you go to the toilet to poop, you don't usually feel the smell and that's because it becomes "normal" for your olfactory system. But when you exit the toilet and reenter in a short period of ...

It is possible (and quite easily achieved) for a patient to drink so much that he dies, irrevocably. You can be anywhere on the fine gradient between not affected and dead, so yes, I dare say on that basis alone that getting intoxicated to the state of not regaining consciousness during surgery would be conceivable. It should be noted, of course, that no ...

The info is a blending of truth and fiction. Reflectors do increase the visibility profile of a person who is wearing a best or some other such item. The fiction comes in the inclusion of inattentive and distracted drivers. Imagine being run over by a truck while jogging on a road, while you are wearing the best and clothing with reflective materials. The ...

I suspect it's all a matter of chance. The business section in Sydney's Sunday Herald newspaper has a feature where a number of different people pick their share portfolios, and week by week the paper follows their performance. The "contestants" include share analysts, financial advisors, sports people, etc, as well as an astrologer (Doreen Daze) and a ...

I will answer "probably". As has only recently become clear through archaeology, there was a very significant bronze age civilization called Tartessos that was likely the prototype for the Atlantean story. This civilization, linked to the Phoenicians, had a virtual monopoly on tin, the critical ingredient in bronze, essentially giving them a basis for a ...

I wasn't able to find any studies that would back up this claim. I did find a compelling refutation of the claim: They’re claiming that certain blenders "unlock" nutrients that your body couldn't get otherwise—a claim that nutritionist Keri Gans, author of The Small Change Diet, says simply isn't true. "It's just a marketing ploy to get you to ...

Nate Silver is wrong on exit polls. In my own blog article, A Reply to Nate Silvers: Ten Reasons why you should ignore exit polls, I write: The Signal is the 52-42% Democratic lead in the 1988-2008 unadjusted presidential state and national exit polls. The Noise is the media propaganda that the Democrats won by 48-46% as shown in the published adjusted ...

Snopes has an article regarding a story told by Lucille Ball of just such a thing happening to her personally. It's listed as 'undetermined' but does seem somewhat plausable. The filling would basically need to function much like a Diode (possible due to dissimilar metals which can form a junction similar to a semiconductor), and the transmission would ...

Violent crime was decreasing in Australia at a stesdy rate before the gun laws. After the gun laws, gun crime rise markedly for 8 years, then returned to following the previous general trend. The rate of violent crime was falling before the laws, and the rate of its decline is now steady again. Some argue it was a heroine drought that caused the spike post ...

Natural vs "Artificial" All vaccines contain the same components as a "natural" infection, immunologically speaking: either a virus (killed or weakened); or a weakened bacterial toxin (toxoid); or the antigen-bearing part of the virus/bacterium (subunit); or a poor antigen attached to a carrier protein (conjugate). This is because of the way the immune ...

Here's a very straightforward reference: The French penal law. Specifically, Article 113-2 makes this law applicable to the full territory of the French republic. And of course it does not employ that thieves get their hands cut off etc. (cf. Article 131). As a consequence the French state must act against any attempts to install islamic law.

No. Registering to vote is a very simple matter. Buying a gun can be simple, but is usually much more involved and involves much more law. There is also a considerable expense in acquiring a gun.

Your friend suggests fasting is a way of flushing toxins. This indicates an assumption that: a) your body is full of toxins, and b) flushing them would be beneficial.

Here is an other theory to explain the phenomenon. I actually don't know if there is any evidence to back it up as I didn't found much on this "leisure sickness". The idea actually came to me by reading this article on immune system ...

The human immune system needs exposure to antigens (external organism that have entered the body) in order to function properly. The danger of using hand sanitizers excessively (especially in young children) is that the immune system does not get to experience as many antigens as it would without the use of sanitizer. A simple graphic illustrates how the ...

“all our social policies are based on the fact that their intelligence is the same as ours – whereas all the testing says not really” can be parsed in two ways; as a question about the level of intelligence ie. how high IQ-score... or as a question about the type of intelligence ie. more a matter of skill. Most will probably think of it as a question about ...

Fast forward to 1930 when he was working out ...

There are two elements to this field of study: The first type of feeling of being watched is called the psychic staring effect (scopaesthesia). a supposed phenomenon in which humans detect being stared at by extrasensory means.

There is another case that might be confusing the issue here: Living organisms are sometimes carbon-dated and generally return non-current ages when this is done. Multiple times I have seen examples of this used as creationist "evidence" that C-14 dates are unreliable when in reality it's nothing of the kind. What happens is that the creature being dated ...

Calcification's effect on water heater efficiency depends on the design of the water heater and the type of calcification.

For circuitry to be able to detect something, that something has to be giving off some sort of energy such as radiation or an emission of a frequency, or has to be able to reflect some sort of energy back from the circuitry such as a pulse of light or sound wave. Even gas detectors including smoke alarms follow this principle as they work by monitoring the ...

Question: Can food type have any effect on weight loss even though net calories would remain constant? Answer: Yes. When you start a low-carb diet (for example < 50 g carbs/day), within the first 1-2 days, your body glycogen stores (about 500 grams) are depleted. Every gram of glycogen is bound to about 4 grams of water, so along with glycogen ...

According to the Dreamworld (QLD, Australia) handlers, tigers are safe enough for them to work with due to familiarity. But any unknown human is potentially food.

Whether voting via the Internet could be made "secure" depends upon what is meant by the term. Historically, a key aspect of the secret ballot is that it should not only be impossible for someone to determine how an individual voted without that person's consent, but it should even be impossible to coerce or entice a person into proving how he or she voted. ...

Kurt Cobain died in '94, and this song was written in '92 or '93.

Since font designers ...
