The Sheepshead fish has teeth that are so human like it feels uncanny and disturbing to look at. It almost looks like they picked up some poor senior's dentures.

2004年、日本の科学者により初めて”完璧な量子テレポーテーション実験”が成功している。 仮に、双子の素粒子(ここまでは光子)AとBを作る。 - これは双子であるため、例えば片方が上向きにスピンしている場合、もう片方は必ず下向きスピンをしているという、対称の物質を持つ。つまりAかBのどちらかを観測できれば、おのずともう片方の状態は観測せずとも知り得るびである。これをエンタングルメントと言う。 素粒子(光子)は観測しない限り、状態が確定しない。いくつもの状態が重なり合っていて、観測するまでのような状態なのか”決まっていない”のである。 これを利用して、Aの光子に、テレポートさせたい情報Cを観測装置内でから見合わせる。この絡み合いの状態を観測するとそれはすなわち”AC”であり、どれだけ距離が離れていようともBの状態は”BC”として確定する。 (この時点ではまだBは観測されていない)その後、Aを観測したな測装置から、Bを観測する観測装置へと通常通信によって光子ACの情報を送信してから、光子Bを観測することで”光子BC”へと変身するのである。 C の情報が事実上、瞬間移動しているため、量子テレポーテーションという名前が付けられた。ただし実際には”通常通信によるの情報の送信”という段階が必要になるため、光を超えた速さでの移動は不可能である。また、最終的に”移動した”光子BCのCという情報は、実際には光子ACに含まれるCの”複製”であり、オリジナルの光子Cは出所不明となってしまっていることも、厳密の瞬間移動とは異なる点である。

there is a theory called "white hole". like the black hole in space. since we don't know what happens to whatever gets into a black hole. there's an idea that another hole on the other side might lead to a completely different universe.

The suffix -core comes from hard core, which at first (1841) referred to broken bricks or stones that formed the hard substratum of roads and foundations. By the 1930s, it was an adjective that described the “base” or “core” of groups such as political parties.

It is impossible to determine the actual length of the Amazon and Nile rivers to determine which is the longest, due to their length not being constant, the difficulty of producing accurate maps in jungles and swamps, the complexity of determining which tributary is the longest, and semantic considerations as to whether features like lakes midstream should count towards the length of a river and if so how

Did you know that the measurements for European Nails and Screws do not actually match the American ones? Although they're ¼ inch, ⅓ inch, and so on, they don't correspond at all with the European measurement! Which goes way more detailed, into millimeters too, over the scale of centimetres!

CRAZY_CATASTROPHE

In super street fighter 2 turbo (1994), Ken (and possibly more characters as well I haven’t checked) actually uses sprites that would later appear in street fighter alpha / zero (1995). His new command kicks have animations that differentiate from the original sf2 sprites, making them seem a bit out of place and “unnaturally smooth” in comparison to the somewhat janky original sf2 animations. My guess is that they wanted to make an updated version of sf2, and just used sprites that were created for sfa when it was still in development.
