Creating Gravity

Brian Greene mentioned this might be only a few years away in Fabric of the Cosmos. Assuming others validate this is true, this is a great step forward for String Theory.

Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of gravity.

Frying Astronauts One Chromosone At a Time

A few conspiracy theorists who claim we never actually went to the Moon mention the inability of the space suits and craft of the time to hold out the cosmic radiation. Do they have enough time to gauge whether a human could survive a trip to Mars and back? Considering Mars no longer has a magnetic field (why it lost its atmosphere – I watch too much NOVA), getting to Mars will not provide a safe haven.

Maybe I am glad I didn’t become an astronaut?

While the astronaut twin is hurtling through space, Cucinotta explains, his chromosomes are exposed to penetrating cosmic rays. This can damage his telomeres—little molecular “caps” on the ends of his DNA. Here on Earth, the loss of telomeres has been linked to aging.

So far, the risk hasn’t been a major concern: The effect on shuttle and space station astronauts, if any, would be very small. These astronauts orbit inside of Earth’s protective magnetic field, which deflects most cosmic rays.

But by 2018, NASA plans to send humans outside of that protective bubble to return to the moon and eventually travel to Mars. Astronauts on those missions could be exposed to cosmic rays for weeks or months at a time. Naturally, NASA is keen to find out whether or not the danger of “radiation aging” really exists, and if so, how to handle it.

Getting To Why

Ultimately motivational books are to get one to understand why we do any particular thing. I ran across this Zachman framework and a thought popped in my head. Its the misunderstandings of what, how, where, who, and when that cause us to not even get to why. Motivational books are about focus on the why and ignore everything else at details.

Back in the fall, I wanted to know whether or not she wanted to go to San Diego for my cousin’s vow renewal. She wanted to know the what, how, who, and when as though they would change the why (she has memory problems so the same questions came up over and over). My point was all that other stuff is immaterial. Other people would take care of all that as long as she decided yea or nay. Ultimately, I wrote down the answers to all the questions and just pointed to the same answer every time she brought it back up. She started to realize I had already answered everything and was waiting on the answer of “Yes, I want to go” or “No, I don’t”.

She answered yes in the end.
