"It's nothing short of a miracle that the modern methods of instruction have not yet entirely strangled youthful curiosity, for this delicate plant, aside from stimulation, stands mainly in need of freedom." |
Homage to Einstein
|
|
Einstein had a visit from his old friend Besso. It was 1905 and by now Einstein was convinced that light must go at the same speed no matter how it was measured. But how could that be? While walking in the mountains Einstein started to explain the problem to Besso. Before he had finished he realised the answer and so special relativity was born. It was just one of the great discoveries made by Einstein in his miracle year. "You see, a wire telegraph is kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And a radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat." |
Relativity Questions and Explanations

"Imagination is more important than knowledge" |
New and Alternative Theories

In 1916, soon after Einstein had completed the general theory of relativity, Arthur Stanley Eddington had just ended his talk: Colleague: "Professor Eddington, you must be one of only three persons in the world who understand relativity!" Relativity has always had the reputation of being difficult but modern education has adapted. Any bright high school student who has understood the chain rule of partial derivatives is ready to learn about the effects of curved space-time. In time she can reach the leading edge of research in cosmology and quantum gravity which remains a great challenge for great minds. |
Research in General Relativity and Cosmology
|

"Finding the underlying laws of physics will be like arriving at the top of the highest mountain in Switzerland. It is a special place from where you can see a long way, but getting there won't mean you have been everywhere. Before you arrive you will be fooled by many false summits. The alpinist knows he must eventually find the true if he has the courage to continue. Can the physicist know as much?" |
