This is why taking a physics class is important. Conservation of momentum and kinetic energy are important. Impulse = momentum or Ft = mv is a linear relationship whereas KE = mv^2 is not. Hence, a little momentum can give a lot of kinetic energy to a low-mass hamster. The velocity of the big ball is not reflective of the velocity the hamster will be launched at.
If you have a source for that, I would be curious to read it. As far as I know, Einstein worked seriously at the patent office, where he was eminently qualified for his job, and did his other work on his own time.
When Einstein was asked how things functioned in the Patent Office, he replied that above all one must be able to express clearly and correctly the wording of the original patent from the description of the discovery and the patentee's claims. The work was not particularly exciting and apart from one or two exceptions it was rather soul destroying. In any case one had to sit every day for eight hours on a stool and in return for that one was given a decent wage.
Einstein felt free; free of academic authority and rules, and thus the Patent Office was a comfortable place for Einstein the free-thinker to hatch his most beautiful theories.
Rudolf Kayser, Einstein's son in-law writes in his biography on Einstein, "He soon discovered that he could find time to devote to his own scientific studies if he did his work in less time. But discretion was necessary, for though authorities may find slow work satisfactory, the saving of time for personal pursuits is officially forbidden.
Worried, Einstein saw to it that the small sheets of paper on which he wrote and figured vanished into his desk - drawer as soon as he heard footsteps approaching behind his door. If he had been discovered, he would have been ridiculed as well as harmed. The Director [Friedrich Haller] would have laughed at him in addition to being angry; he was too great a positivist to think much of speculative science".
It appears that Einstein used to write his notes on "small sheets of papers", because later one of the students at the University of Zurich described him entering class with
notes "the size of a visiting card on which he had scribbled what he wanted to tell us". On these papers Einstein very likely wrote his path breaking 1905 papers;
and these small sheets of papers the size of visiting cards could perfectly enter his desk-drawer without being discovered by Haller.
Time to celebrate Maymo's birthday! Since Maymo loved getting 100 balls last year, we decided to up the ante and fill a DIY ball pit with 1000+ rainbow-colored balls (because gay marriage!). At first Maymo thinks it's just an ordinary day with us rearranging the furniture, but he perks up when he sees the box filled with 1000+ colorful balls. Maymo's reaction is hilarious and predictably cute, with the funny dog jumping into the ball pit, excitedly wagging his tail and playing until he is tuckered out.
