The origin of gravitation
zheng sheng ming


In the natural world, people have discovered four kinds of forces: the electromagnetic force, the gravitation, the weak force, and the strong force.Although the gravitation has been discovered more than three hundred years, its mechanism of origin is unclear until today. While investigating the origin of gravitation, I discovered that the moving photons produce gravitation. This discovery reveals the origin of gravitation. Meanwhile my discovery indicated that light interference fringes are produced by the gravitation which is created by moving photons. In other words, my discovery demonstrated that light is a particle, but is not a wave-particle duality. Furthermore, application of this discovery to other moving particles appears a similar effect. All these show the origin of gravitation and reveal the essence of matter wave.Along this way,I also unify the gravitation and electromagnetic...

Forest Gardens and Polytunnels by Anonymous on May 18th, 2009, 6:05 am
Yesterday was a mixed kinda day.

I spent a very pleasant afternoon on a tour of a forest garden in Devon at the Agroforestry Research Trust. Very beautiful forest garden, established fifteen years ago and coming nicely into maturity

Library Books by zetreque on March 27th, 2018, 6:07 pm
My alma mater has decided to get rid of 8000 books from it's library. I find it incredibly sad that this happens because I know so many students half-arse their reports and don't make use of this wonderful database of knowledge. One of the criteria for getting rid of the book is if it hasn't been checked out in a while. I am shocked by some of the books being gotten rid of. The books are being donated to an organization that is just going to try to sell them online. The other sad thing is, no one seems interested in these books or there is a lack of communication of getting rid of the books.

I have been going in regularly and going through them all and allowed to take any I desire. This is difficult because there is so much good stuff but I will not have the time to read it all. There is also so much knowledge in books that you just can't find online!!!!

Today they were getting rid of a book that I had just used for one of my classes to write a report on. I saved it to at least give to...

Round the World to Vietnam by Anonymous on May 22nd, 2009, 7:11 pm
Hey All,

This summer, I will be working with Thomas Hales on his work to proof of the Kepler conjecture. He'll be based out of Hanoi, Vietnam.

Now, sadly University of Pittsburg, which is arranging the research program this summer, couldn't arrange for a flight to Vietnam for me from Amsterdam, since it was out of budget. They could only manage a flight out of the US. However, I had a frequent flyer ticket out of Amsterdam to Logan Airport, so I'll be flying to the US before flying to Vietnam.

This flight plan is kind of crazy:
Schiphol, Amsterdam, NL -> O'Hare, Chicago, IL
O'Hare, Chicago, IL -> Logan, Boston, MA
Logan, Boston, MA -> JFK Intl Airport, New York, NY
JFK Intl Airport, New York, NY -> Hong Kong Intl. Airport, Hong Kong, China
Hong Kong Intl. Airport, Hong Kong, China -> Noi Bai, Hanoi, Vietnam

And here's the path on google maps... estimated around 13,700 miles......

Cosmic Engineering (Relativity "Controversy" 2) by BurtJordaan on November 9th, 2012, 6:55 am
In my prior Post, I have discussed the present scientific view on the relativity of simultaneity and more specifically the misstatement: “the actual one-way speed of light (in vacuum) equals the constant ‘c’ in every inertial frame of reference”. I have shown that Einstein chose it as a very convenient convention and that it is in fact the best convention to choose – it makes the physics “as simple as possible, but not simpler”. In this delivery of Cosmic Engineering, I want to discuss an equally common misstatement about the actual tick rates of clocks in relative inertial motion.

Relativity 'controversy' 2The actual tick rates of clocks in relative inertial motion in free space are necessarily different”. The correct interpretation of the facts is that for clocks moving inertially in free space, it is impossible to determine any tick rate difference, because they can only meet once. In order to compare tick rates, one of the two cl...
