it’s science time

Technically, no, since they don’t have anuses. Then again, they do have cloaca, which is the multi-purpose exit point for both waste and reproductive fluid…and thus, it serves the purpose of the anus. The male has two hemipenes, stored in the tail, and inserts one of the pair into the female’s cloaca in mating.

I suppose it depends on how you look at it.

Seeing this presented as something other than.. well, traditional math- I might actually remember it! :3 Very cute!

this made me really sad

…Ah, heartbreaking as this is, there is one thing. The asymptote graph is technically inaccurate, - as said, the lines get closer and closer, without meeting, but an asymptote (to a plane curve) is actually a straight line in which the distance between the line and the curve will approach zero as they tend to infinity. These are the typical asymptote graphs, of course - but in the example above, two curves that approach each other at their minimum points are depicted, which…well, isn’t a representation of asymptotes. Rather, they’d look like this:

The asymptotes to the above graphs are y=0 and x=0. The larger the value (approaching infinity), the closer the curve to the axis, but they do not meet. The relationship isn’t between the two curves, as implied by the graphic!

Not to mention, a curve can actually intercept its asymptote. For example, take the graph of y=x(e^-x): you can see it here. Technically, y=0 is a horizontal asymptote by appeal to calculus (for large x, f(x) may be made as small as possible, and yet will always be positive). As you can plainly see, however, the curve passes through (0,0). And there we have it - a curve intersecting its asymptote.   

…Oh dear, I think I’ve gotten carried away.

Heterochromia.

Or, more specifically, central heterochromia, in which thecentral zone of the iris is a different colour than the midperipheral zone, with the exterior colour being the iris’ ‘true colour’. A little-known fact is that the word is actually a blanket term, and the condition may also occur in the hair and skin - when it occurs in the iris, it’s specifically known as heterochromia iridum or iridis. 

There are, of course, a variety of causes, ranging from inherited genetic traits, genetic mosaicism, disease, or injury. Generally, however, an eye that is low in melanin is often subject to central heterochromia.

2198. Odori-don. Odori-don is a sushi dish with a dead octopus that dances when soy sauce is poured on it. WHAT THE…

Oh, now this is interesting! To understand the science behind this curious phenomenon, think of the soy sauce - which has a high sodium content - as jolting the squid’s tentacles with tiny amounts of electricity. The energy in question lies within ions contained in the sauce’s aforementioned sodium content, which are used in cells to create voltage differences. As the squid is served fresh, the cells inside are still active and when the sodium is applied, the signals across the nerve cell membranes are temporarily reactivated causing the squid to “dance.”
