E=mc2, the formula
Not about Einstein, not a biography
Equation had a large part in the race for a nuclear bomb.
He was poor. He was married with two children. They had to give the first child up to adoption. He worked as a clerk in the Bern patent office.
He got average to good results. He had a conflict with the professor.
In his office: He had a drawer with his notes. All the research was theoretical.
German physics journal: Annalen der Physik.
Bookbinder
He bound the lecture notes he took for Davy and gave the book to him
First, he gave him a job as a lab assistant and supported him, but later he was jealous of his success
He had no formal education
He believed in circles from his religion and had no training in Newtonian physics (forces depicted in straight lines)
Electrical engine; summer of 1821
In a closed system, the amount of energy stays unchanged.
There is energy in mass itself. The amount of energy and mass is always the same.
Most of the main typographical symbols we use were in place by the end of the Middle Ages. Bibles of the fourteenth century often had text that looked much like telegrams
This is how Einstein used the " = " in his 1905 equation as well. The Victorians had thought they'd found all possible sources of energy there were: chemical energy, heat energy, magnetic energy, and the rest. But by 1905 Einstein could say, No, there is another place you can look where you'll find more. His equation was like a telescope to lead there, but the hiding place wasn't far away in outer space.
Very disciplined administrative clerk, a romantic
It got heavier because rusting added oxygen to the iron
Isaac Newton
The law of the conservation of mass
Because he had worked for the French King, he had been responsible for building a wall around Paris
They are two separate domains. The law of conservation applies to each separately.
By thinking about the speed of light
Galileo Galilei
He analysed the movement of the moons of Jupiter and realised that light from the moons took time to reach earth
He was outside the astronomy establishment in Copenhagen
He rejected Roemer's findings
300'000 km/sec
Similar personality
Electromagnetic waves in the visible spectrum
It is the ultimate speed limit. It is a physical constant, that can't be surpassed.
Because if you pour more energy into an object, it just gets heavier as it moves faster.
It is complete stillness. You can't move less than not at all.
It increases in size.
energy and mass
Because the effect is not noticeable in ordinary life.
French author of the 18th century
