E really does equal MC squared

I don't suppose that many people will spend 100 years or more proving that something I either said or wrote was true. That I suppose is because I was never a patent clerk in some deathly dull small Swiss town in the early 20th century, before technology, when all I had to do for hour after hour was prove some mathematical construct involving three things that I called E, M and C. Three things that had never been thought of much before and the purpose of which could never be used for decades if not centuries. But then again my name is not Albert Einstein.

So instead of inscribing into huge books in the patent office endless patents of new Swiss clocks, or chocolate recipes or yodelling tunes.. or whatever it was Einstein should have been doing at work, this shirker came up with:

The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing.

In a previous post, I mentioned that I gave up science in favour of Latin and classics generally at age 11 so I have not the slightest idea why this is important, revolutionary, or even interesting. But it is, for just this week, yet another group of scientists proved it again. Or rather a part of it anyway.

Here's the full article and it really does make me happy to know that something that was done so long ago simply trying to solve a tricky mental hypothesis, and really on the back of an envelope (maybe addressed to the patent office by some hopeful trying to register a new patent for fruit and nut chocolate) is so relevant today. And... and this is the really amazing part to me... using only the most cutting edge technology and equipment that wasn't even thought about when Einstein originally developed his theory.

'It's been nearly 30 years in the making, but scientists with the Very Large Telescope (VLT) collaboration in the Atacama Desert in Chile have now measured, for the very first time, the unique orbit of a star orbiting the supermassive black hole believed to lie at the center of our Milky Way galaxy. The path of the star (known as S2) traces a distinctive rosette-shaped pattern (similar to a spirograph), in keeping with one of the central predictions of Albert Einstein's general theory of relativity.'

A spirograph. Many planets do have orbits like this.

There's more to it than this of course, but this is the essence of the piece. Relativity has been something that had been doing the rounds for quite a while, but it was Einstein who tied it down.

'When Einstein developed his general theory of relativity, he proposed three classical tests to confirm its validity. One was the deflection of light by the Sun. Since massive objects warp and curve spacetime, light will follow a curved path around massive objects. This prediction was confirmed in 1919 with that year's solar eclipse, thanks to Sir Arthur Eddington's expedition to measure the gravitational deflection of starlight passing near the Sun. The confirmation made headlines around the world, and Einstein became a household name.'

Mercury's orbit... just like a spirograph

This is just wonderful! Well done again... no, yet again, Albert!
