- IDEA 1 OF 8
A rebel with imagination
Isaacson portrays Einstein as a curious, rebellious thinker who disliked rigid schooling and authority.
His imagination and willingness to question accepted ideas allowed him to see the universe in new ways.
- IDEA 2 OF 8
A clerk changed physics
Einstein worked as a clerk at a patent office in Bern, examining inventions.
In his spare time, he developed ideas that transformed physics. Isaacson shows that having a quiet job gave him time to think freely about big questions.
- IDEA 3 OF 8
The miracle year of 1905
In 1905, Einstein published papers on light, atoms and special relativity, including the famous equation linking energy and mass.
This miracle year changed science. Isaacson shows that it is rare for one person to change several fields in a single year.
- IDEA 4 OF 8
Time and space are relative
Einstein's special relativity showed that time and space depend on the observer's motion.
Clocks run slower at high speeds. Isaacson explains that these effects seem strange to us only because we rarely move at such speeds.
- IDEA 5 OF 8
Gravity bends space
Einstein's general relativity, completed in 1915, explained gravity as the bending of space and time by mass.
This was a revolutionary idea. Isaacson explains that objects follow curved paths because of this bending, not because a force pulls them.
- IDEA 6 OF 8
An eclipse made him famous
In 1919, observations during a solar eclipse confirmed that light bends near the sun, as Einstein predicted.
He became world-famous overnight. Isaacson shows that this proof of his theory made newspapers around the world celebrate him.
- IDEA 7 OF 8
He questioned quantum theory
Einstein helped start quantum theory but disagreed with its later randomness.
He debated with other physicists for years. Isaacson shows that he felt nature should follow clear rules, and he could not easily accept chance as the final answer.
- IDEA 8 OF 8
Thought experiments led the way
Einstein often imagined scenarios, like riding alongside a beam of light, to test ideas.
These thought experiments guided his discoveries. Isaacson shows that imagination, as much as maths, was what helped him find new ideas.
