"Hi Lauryn, Before you get all condescending, have you been to the equator and seen for yourself? I have. In ecuador to be exact. In the southern hemisphere it spins clockwise, on the equator it drains straight down, and in the north it spins anticlockwise. I didn`t believe it untill I actually saw it with my own eyes. I was pretty skeptical (have a science degree), but yeah, it actually happens. "

I`ve seen all those scenarios where I live.

The toilet one is wrong! I`ve seen experiments on TV demonstrating the direction of the water each side of the equator and it does go in opposite directions. It also doesn`t spin at all when you`re on the equator itself.

"So what about white dwarfs?"

They still have a dominant color depending on their temperature. Newly formed white dwarfs are quite hot and thus are blue. As they cool they go through green, yellow, orange, red, and gradually fade to infra red (brown dwarfs).

A star closely approximates a blackbody in its energy distribution curve. The wavelength of peak of the curve depends on temperature. There`s a good article on it here.

For a star to be white, it would have to radiate equal amounts of energy at all visible wavelengths, which never happens in nature.

the tounge thing is not 100% wrong...at least not for me. if i touch something sweet to the tip of my tounge i can taste it, but if i touch it to the sides or the back i can not. If i touch bitter chocolate to the tip of my tounge i can not taste it, but i will taste it if i place it on the back of my tounge. I know that the tounge has taste receptors through out the entire surface, but it seems as if those zones really do have more of a certain type than others

@OldOllie i`m pretty sure that the peak wavelength of 475-500 nm is blue green, mixture of which is white, after scattered by air molecules it will shift to the yellow region of spectrum. Never mind that, your conclusion "no star is white" is just wrong. And also, they didn`t say that Coriolis effect in flushing toilet is unreal.You are right, the effect is greater the further away from the equator. Just do a simple calculation of earth`s radial freq with water flow`s velocity and the swirling radius of water you will see that the resulting moment of Coriolis force is in the order of 10^(-7)N.m (maybe overestimating it) and compare it to the initial momentum of the water itself. The things that really determine the direction in which water leaves your toilet are the shape of the bowl and the angle at which the liquid initially enters that bowl. The butterfly flapping wings is also real and observable lol

8 is wrong, there are no eggs in Twinkies, and likely little flour as they use a near fully artificial sponge cake and icing recipe now-a-days. I`m not sure the shelf life, but I wouldn`t be surprised it ~1 month was an accurate estimate.

Okay, 6 and 9 are wrong.

The sun has a peak wavelength of about 475-500nm corresponding to a yellow-green color. All stars have a predominant color from deep red to blue. No star is white.

The Coriolis effect is small on small quantities of water, but it is real and observable. Take a round tub; drill a hole in the center of the bottom; put it on a couple of saw horses; put a stopper in the hole from below; fill it with water; let it stand for a few hours; and pull the plug. The water will start spinning counter-clockwise in the northern hemisphere, and clockwise in the southern hemisphere. The effect is more pronounced the farther you get from the equator.

If you start the water swirling in the opposite direction, it will continue in that direction since you have imparted more angular momentum to the system than what was there from the Coriolis effect. However, for a toilet, it`s better to go with the water`s natural tendency than to fight against it.

#1 is true, but it neglects to mention that muscle does turn to flab when you stop exercising. That is, you lose tone, and the muscle becomes more "floppy," making it look kind of like fat.

I`m not quite sure about the tongue thing...I work at a coffee shop, and different types of coffee hit the tongue in different areas. The stronger (read:bitter) coffees usually hit the back of the tongue, whereas the taste for sweeter/herbal tends to be strongest at the front and sides.

That brain myth has always irritated me. Although often when people mention it, they might be referring to the capacity that our brain has to learn and remember. In that sense the statistic is clearly way, way less than 10%.

"Mrbateman40" is somewhat correct about the sun. Our sun is made of plasma. It`s classified as a G-5 on the Hertzsprung–Russell diagram at a temp of 5000-6000k in fact making it a orange/yellow color. In order for it to be white it would have to be an F5-A5 class at a temp of 7000-1000k and would have to be a lot bigger approaching sub-giant and start to go off the Main Sequence.

I could have sworn I`ve SEEN toilet bowl water spinning counter-clockwise in Australia, on something of a reputable source like the Discovery channel, and having them cite hemisphere location as the cause. Here`s their own website, however, dispelling the myth or `clarifying` the `legend`:

Toilet

Perhaps I mistook correlation for cause?

And PS: Einstein didn`t mean we literally use 10% of our brain, he meant we used 10% of it`s potential. They even admitted themselves (in a round-a-bout way) that we use our brain less (read: not less of our brain) when we are sleeping.

The Sun is a ball of fire held together by gravity and the pressure cause from nuclear fusion. There are varying colors of sun`s depending on their size and how hot they are. Generally the hotter the star the larger. our sun happens to have a surface temperature of about 10,000 degrees, which happens to emit a red fire. It`s not white. or Turquoise. The hotter/larger suns are more light blue/turquoiseish, and the hottest of suns can burn ultra violet. soooo.

the sun is actually more turquoise than white, its due to the emission spectra of the fusion in the suns atmosphere

I`ll say in reply to #4 that while cutting off dead hair doesn`t cause hair to grow, colder skin does. They`ve done studies with white rabbits where they place an ice pack on the bunny, and the hair in that area grows in black. I would imagine it`s much the same to shave off your hair, causing the temp in the specific area to get colder. this only seems to affect leg/back/chest/face hair, not to the hair on the top of your head. Otherwise balding people would tear out their hair in clumps.

I think that`s why a guy can grow a mustache, then a beard, and they`ll be about the same length after a few months.

@BigMordecai It`s generally agreed upon that certain regions of the brain have Very specific functions. I thought this myth pertained to the school of thought: that of 100% of the brain, x% (of either a specific region(s), or of the total) was dedicated to CONSCIOUS brain functions because it`s rather obvious that the brain regulates a lot of subconscious functions (like heart rate or breathing). I argue that we DON`T and CAN`T use the rest, thus the x%. Because the energy is being used for other regulated functions that are difficult to change. You can hold your breath until you pass out, but can you keep holding it after that? No.

It`s hardly abstract, but we don`t know enough about the brain yet to point to all these places on a model. It`s not like we average Joes and Janes have the terminology to discuss anything about the brain in more specific terms anyway.

@Lobotomy The sun is actually a black body meaning it radiates all wavelengths of light, thus is white.
@Everyone who makes the we only use x% of the brain. The statement is bullpoo but you have to contextualize your measurement. You will never use that low because you are constantly receiving sensory information and sending it. You are also regulating hormones hunger fear etc. as a lot of the brain is used. If one uses an MRI to scan regions then one discovers much more activity. Probably the best definition is neurons firing which this would describe. @Nexus Letum- the brain isn`t RAM, there is not some abstract brain space. @NoxasRisen You don`t know anything about the brain.

With a surface temperature of 6000 K the sun actually is yellow, even if seen from space. The effect which tints our sky blue with scattered sunlight is called Rayleigh scattering. At dusk and dawn, when the sunrays are passing through a lot of air, that leaves the sun itself with the complementary colours of blue and violet, which are orange and red.

In reference to only using 10% of your brain...

I guess you COULD make the argument that you only use 10% of your brain for conscious thought. I know you`re brain is constantly monitoring pretty much every cell in the body and making sure things stay in homeostatic balance.

The 10% of the brain section is ridiculous. Who`s to say if we did only use ten percent it would all be in one localized area? "Damage to any part of the brain have profound effects on the person who suffers that damage." So who`s to say we couldn`t be putting those tiny areas to much better use?

I thought the myth always went 20% of the brain, not 10%. Also twinkies have a huge shelf life. Just because it goes stale (read: not spoiled), doesn`t mean you can`t still safely eat it. Water goes stale too, and so long as it wasn`t kept in plastic it`s still okay to drink.

@LandoGriffin Really? I always figured it was a percentage based on "conscious" use of brain space, like memorized facts, decision making, or learned skills. Excluding emotions, chemical regulation, and other routine functions that I assumed made up most of brain usage.

the 10% of your brain thing refers to 10% of the possible connections we could make. Like if you learned to speak English only as a baby, you will never be able to speak Hindi without an accent because you can`t hear or make all the sounds, just like a Japanese speaker can`t pronounce "R" or "L" in English.

@green_batman, wo asked: "why is it that photos of the sun always show it as a yellow-orange color?"

Photographic images of the sun are usually done with very narrow band filters, i.e. they are basically black-and-white pictures at a particular wavelength. Since black-and-white is boring, these images are often tinted yellow or orange, just because we are used to the sun being yellow. Other colours like green or blue are used as well to indicate shorter wavelength.

I always assumed that 10% referred to capacity and not actual brain mass usage. It`s like a car engine that is idling. Although the entire engine is running, it is not being used to it`s fullest capacity

That would be sashimi, not sushi. Sashimi is just one of the many possible toppings on sushi. The wording of the article was awkward. What they meant is that sushi isn`t raw fish. Sashimi is raw fish. Sushi can be made with anything.

No way. I`ve personally seen over 6 twinkies that someone saved for well over 4 years now.

They were lazy, put them on a stick, and brought them as dessert (seriously). He brought them back and they`ve been on a shelf ever since, opened. Still looks fresh, but they feel a bit hard.
