The year 1905 was certainly a busy one for Albert Einstein. He had at least five papers published during that time. Not only would any scientist be proud to be so prolific, but Einstein was able to enjoy the fact these papers fundamentally changed the way we understood how the Universe worked.


Today is the anniversary of when the journal "Annalen der Physik" (or "Annals of Physics" in English) received Einstein's paper on mass-energy equivalence. What’s that, you may ask? Well, it’s probably better known for its most famous equation: E=mc2.

We doubt Einstein would have guessed that his equation would end up as part of popular culture – the subject of everything from T-shirts to bumper stickers. He might have envisioned, however, that nearly a hundred years later, it would still serve as the backbone of modern physics. In fact, we recognize how much influence Einstein has had on all that the Chandra mission does that we put together this package as a small ode.

So thanks, Albert, for your most excellent equation. We hope you don’t mind us using it.

A very good year

Indeed he was great scientist or I can say he is a great scientist. Only because of him we get to know the the biggest equation of energy.Thanks to him for his great contribution in science.
