Zombie apocalypse statistics

When buried six feet down, without a coffin, in ordinary soil, an unembalmed adult normally takes eight to twelve years to decompose to a skeleton. However if placed in a coffin the body can take many years longer, depending on type of wood used. For example a solid oak coffin will hughly slow down the process.

Assuming everyone is buried without a coffin and in normal soil, there would be 31517016 zombies purely risen from the dead. You would be wondering why 31517016 zombies, the math is, 2626418 is the average number of people dieing per annum and 12 is the number for years (maximum) for a body to decompose, 2626418 × 12 = 31517016 All the dead people buried before 12 years ago, would have already decompose and will not be considered undead. So with 7 Billion living humans (with modern technology) verses 31517016 undead classic zombies, who as slow, witless and only react to sound, We can survive a zombie apocalypse with ease.

BUT

If the undead is considered to be all the dead people till now, that would be 107 billion zombie against 7 billion zombie. Making that around 15 zombies for every 1 living human. The chances of surviving is slim.

Plenty sit still. Hunger is a wanderer.

And where the moon goes when it sets

In their newest video, the Slow Mo Guys recreated one of my favorite effects: vibration-driven droplet ejection. For this, they use a Chinese spouting bowl, which has handles that the player rubs after partially filling the bowl with water. By rubbing, a user excites a vibrational mode in the bowl. Watch the GIFs above and you can actually see the bowl deforming steadily back and forth. This is the fundamental mode, and it’s the same kind of vibration you’d get from, say, ringing a bell. 

Without a high-speed camera, the bowl’s vibration is pretty hard to see, but it’s readily apparent from the water’s behavior in the bowl. In the video, Gav and Dan comment that the ripples (actually Faraday waves) on the water always start from the same four spots. That’s a direct result of the bowl’s movement; we see the waves starting from the points where the bowl is moving the most, the antinodes. In theory, at least, you could see different generation points if you manage to excite one of the bowl’s higher harmonics. The best part, of course, is that, once the vibration has reached a high enough amplitude, the droplets spontaneously start jumping from the water surface!

Physicist Create a Fluid With Negative Mass

Physicists from Washington State university have created a liquid with negative mass meaning that when you push it, instead of accelerating in that direction, it accelerates backwards.

Matter can have a negative mass much the same way that particles can be negatively charged. Newton’s second law of motion (F=ma) tells us that mass will accelerate in the direction of the force so we can deduce that matter with a negative mass would do the opposite and accelerate against the force.

To create the conditions for negative mass, Peter Engels and his team started by cooling rubidium atoms to a Bose-Einstein condensate meaning they reached very near absolute 0. The researchers used lasers to trap the atoms in an area less than 100 microns across and allow high energy particles to escape cooling them further. Then to create negative mass, the physicists applied a second set of lasers to change the way atoms spin back and forth. They then removed the first set of lasers causing the rubidium to rush out and appear to hit some sort of invisible wall; behaving as if it had a negative mass.

What’s great about this is the control we have over the negative mass without any other complications. This gives us a new tool we can use to engineer experiments in astrophysics looking at neutron stars, black holes, dark energy and a lot more.
