Richard Feynman: “high, real good physics” requires “solid lengths of time” and “concentration”

Standard

In an interview Richard Feynman says:

To do high, real good physics work you do need absolutely solid lengths of time, so that when you’re putting ideas together which are vague and hard to remember, it’s very much like building a house of cards and each of the cards is shaky, and if you forget one of them the whole thing collapses again. You don’t know how you got there and you have to build them up again, and if you’re interrupted and kind of forget half the idea of how the cards went together—your cards being different-type parts of the ideas, ideas of different kinds that have to go together to build up the idea—the main point is, you put the stuff together, it’s quite a tower and it’s easy [for it] to slip, it needs a lot of concentration—that is, solid time to think—and if you’ve got a job in administrating anything like that, then you don’t have the solid time. So I have invented another myth for myself—that I’m irresponsible. I tell everybody, I don’t do anything. If anybody asks me to be on a committee to take care of admissions, no, I’m irresponsible, I don’t give a damn about the students—of course I give a damn about the students but I know that somebody else’ll do it—and I take the view, “Let George do it,” a view which you’re not supposed to take, okay, because that’s not right to do, but I do that because I like to do physics and I want to see if I can still do it, and so I’m selfish, okay? I want to do my physics.

You can find this between 08:22 – 09:56 of part 4 or or 38:16 – 39:52 of the full interview:

The interview is known as “The Pleasure Of Finding Things Out”. Here is the interview divided into 5 parts.

And here’s the (original) full interview from The Science Foundation’s YouTube channel.

Moreover, “John Yudkin: the man who tried to warn us about sugar” (read distraction-free in Readability) is an interesting article on the subject.

This work is very interesting and will definitely help in the detection of widespread diseases like Tuberculosis (TB) in developing countries. The only primary obstacle that needs a real solution is countering the monopoly by vaccine manufacturers.

“Morpheus Project” for non-toxic spacecraft propellant and “Loon” for Internet from the Stratosphere

Standard

Morpheus Lander (a NASA JSC project)

Morpheus is a vertical test bed vehicle demonstrating new green propellant propulsion systems and autonomous landing and hazard detection technology. Designed, developed, manufactured and operated in-house by engineers at NASA’s Johnson Space Center, the Morpheus Project represents not only a vehicle to advance technologies, but also an opportunity to try out “lean development” engineering practices.

Project Loon: The Technology (a Google project)

We believe it’s possible to create a ring of balloons that fly around the globe on the stratospheric winds and provide Internet access to the earth below. Balloons present some really hard science problems, but we’re excited about the progress so far.
