In Greek myths, Heracles' 10th labor was to travel to the island of Erytheia, and steal the cattle of Geryon. Depending on the author, Geryon has been alternatively described as a man with three bodies and three heads, three heads and one body, or even three bodies and one head. #MythologyMonday
In Greek myth, while Heracles was battling the Hydra, Hera sent a monstrous crab to distract him. The crab clawed Heracles' foot, but the demigod kicked it to pieces while still focusing on the Hydra. Hera afterwards turned the crab into the constellation Cancer. #MythologyMonday#31DaysofHaunting

I often like to do thought experiments while #cycling and sometimes I can’t think all the way through to the end of the answer. Here’s a recent one for #physicists who specialize in #relativity. A #bike's #wheel rotates such that the bit in contact with the #road is instantaneously at rest with respect to the #ground (no skidding), at least in #NewtonianMechanics. On the other hand, the bit diametrically opposite to it is moving at precisely twice the speed of the #bicycle...
Now, imagine a #cyclist with the speed of #Hermes and the strength of #Heracles who can go as fast as possible but within the confines of what we know about the real world. If the above still holds, about the #tyres of the bike, then, in the limit, the top of the wheel can go no faster than the speed of light, c, and the mass of that bit of the wheel increases without bound. Does that mean that the bike itself cannot exceed c/2?
