Throwback Thursday: When We Changed The Laws Of Gravity

“This Friday marks the 96th anniversary of one of the most important historical events in all of science. We can look back at all the time that’s passed, and find that every single prediction of Einstein’s gravity that’s ever been tested — from gravitational lensing to binary pulsar decay to time dilation in a gravitational field — has confirmed General Relativity as perhaps the most successful physical theory of all-time. It all goes back to one fateful day, nearly a century ago, and our understanding of the Universe has never been the same since.”

That time when, after 200+ years, we changed the laws of gravity. THAT’S a throwback thursday/flashback friday!

I made an AU video for 10 and 11 xxx

yellowbessie asked:

Have you ever seen Einstein and Eddington? (The 100th anniversary of the 2nd Battle of Ypres was a few weeks ago, which made me think of it :( Also, I'm not sure how much I agree with their portrayal of Eddington, based on other things I've read, but David Tennant did a very good job regardless.)

Yes, I have seen that one. It’s actually one of my favorite films of David Tennant’s. And yes he did an very fine job of playing Arthur Eddington who was a very important scientist who got pushed under the radar when Einstein came into the picture of the scientific world. I mean here is a gif of him in one of my scenes from that movie where he was talking about the importance of science and learning to his fellow colleagues after what had happened at the battle of Ypres. 

The mind-stuff of the world is, of course, something more general than our individual conscious minds. The mind-stuff is not spread in space and time; these are part of the cyclic scheme ultimately derived out of it. It is necessary to keep reminding ourselves that all knowledge of our environment from which the world of physics is constructed, has entered in the form of messages transmitted along the nerves to the seat of consciousness. Consciousness is not sharply defined, but fades into subconsciousness; and beyond that we must postulate something indefinite but yet continuous with our mental nature. It is difficult for the matter-of-fact physicist to accept the view that the substratum of everything is of mental character. But no one can deny that mind is the first and most direct thing in our experience, and all else is remote inference.

The House Judiciary Committee is considering the third version of the USA Freedom Act in the last two years. In its current form, the bill effectively acts as if the Snowden revelations and several independent reviews of the PATRIOT Act Sec. 215 metadata program never happened.

The bill grants the government sweeping “emergency” collection authority not tied to an imminent threat of death or bodily harm, and allows the government to retain U.S. Person call detail records. It fails to address bulk collection and retention of US Person records, lacks mandatory US Person data destruction and audit compliance provisions, contains no protections for national security whistleblowers, has no bar on government-imposed “back doors”, does not bar targeting based solely on use of internet anonymizing technology, and does not address the recently revealed DEA telephony metadata program.

In a ten-and-a-half-hour-long filibuster over the NSA surveillance programs authorized under the Patriot Act yesterday, Sen. Rand Paul cited analysis by former CIA analyst and current Cato policy analyst Patrick G. Eddington.

“One thing is certain: the fight over reforming our nation’s surveillance laws is about to get much more intense, and quickly,” said Eddington.





說來簡單,可是當時正在打第一次世界大戰,而下次最適合觀測的日全食將會發生於巴西海岸到赤道非洲這帶狀區域;要冒著戰火,跋山涉水遠赴天涯海角可是一件危險任務。結果熱心出任務的不是愛因斯坦的德國同胞,反而是敵對國的英國天文學家愛丁頓(Arthur S. Eddington)。


愛因斯坦收到電報那一天,正和研究生施耐德(Ilse Schneider)討論。她緊張的問愛因斯坦萬一比對結果顯示廣義相對論是錯的,那怎麼辦?愛因斯坦微笑答道:「那我會為親愛的上帝感到遺憾,因為我的理論是正確的。」
