How to paint the MONA LISA with MS PAINT

Neal Adams Science project

The creator of this video is proposing that the planet Earth has grown over time. The video provides one piece of evidence for his proposal. He has other videos (on the moon and Mars for example) suggesting that every planet has grown over time. The interesting thing about his proposal is that there is no current mechanism that could explain how a planet could "inflate" like this.

Helicopters in trouble

In all three cases, the helicopter gets hung up on something. In the first, the helicopter is not unstrapped properly from the net. In the second one, it is towing something. In the third one, it gets caught on a handrail. Once a helicopter tips, it can become unstable and bad things happen.

The disposal of sodium after WWII

The reaction looks like this:

2Na(solid) + 2H₂O → 2NaOH + H2(gas)

In other words, the sodium turns into sodium hydroxide and hydrogen gas, and the reaction gives off a LOT of heat. That heat boils water and can also ignite the hydrogen.

Robots

This walking robot does not look very good compared to ASIMO. The difference is that ASIMO is not balancing. This robot is learning to walk the same way humans do - by falling forward and continuously rebalancing. It may be a year or two before this is perfected, but once perfected it will mean that robots start to look graceful rather than stilted.
