[b]1. The problem. Okay, here's the question: 'An air bubble situated at the bottom of an open kerosene tank rises to the top surface. It is observed that at the top, the volume of the bubble is thrice it's initial volume. If the atmospheric pressure is 72cm of Hg, and mercury is 17 times...

Hi! Let's say I have a bubble chamber and a particle traveling in it. I know the trajectory of the particle, because I can see the bubbles. But if I measure the time elapsed between the appearance of the first bubble and of the last one, I know how much time the particle took to follow the...

Near my room there's a bee trap where bees fly into a kind of bottle half filled with juice and they eventually drown. For the first 2 days after drowning the bee floats. Then it sinks for a few days, and then it floats to the top again and is covered in bubbles. Why does this happen? Thanks.

i remember once seeing on tv (fiction) how a man threatened another with a syringe and said he would inject the other with air and that 2 ccm would be enough to kill, if i remember correctly what happens if air gets into your circulatory system ? i imagine it would be ok until it is pumped...

It's been hypothesized that, at a high enough energy density (say, in a collision of particles), a bubble of true vacuum could be formed, which would then grow at the speed of light and envelop our universe, which is currently in a false vacuum, thus making all matter disintegrate. Is this possible?

From general research, I have seen a certain pattern emerge that causes me to re-evaluate how I look at the universe. It's easier to see with visuals, but I will try to describe it here. I believe some of the abstractions can lead to a better understanding of the structure of the universe, or at...
