Dark side of the sun looks like it could be good. Will have to watch.

I remember that there was something like this when I was in 7th or 8th grade too.0 -

Okay, so I was reading about theories on Mars water and came across this interesting opt-ed piece on the collective progression of research. More so the that change from a stalwart front of discovery to a (subjectively) stranded, or thin collection of scientists.Here there is a paradox: Today, there are many more scientists, and much more money is spent on research, yet the pace of fundamental innovation, the kinds of theories and engineering practices that will feed the pipeline of future progress, appears, to some observers, including us, to be slowing. Why might that be the case?
Interesting read, if your into this science.

I only read through that quickly, but one thing I didn't see mentioned was war. "Necessity is the mother of invention", and all that. An awful lot of technological progress has been due to war or the aftermath of it, and there hasn't been such a need for that pace of development in the past 50 years. (I realise that many of the areas of research mentioned might not necessarily seem related to that sort of endeavor, but making your armies and weapons more efficient trickles down into many other things eventually.)
I have an interesting book written in the 50's about the future of rocket development, which was so driven by the Cold War that the author couldn't really describe the concepts he was trying to explain since "the enemy" might read it and know what America was up to!0 -

Agree with you on all of that. The article could be considered fringe science opinion as there is always strong suggestion that gov-sci is where the real cutting edge development and break-thru happen. And as you mention, very much driven by military wants and needs. I remember reading a 1960's book on NERVA engines for space exploration. It was presented as a generic hypothetical piece, with some mathematics, but there was a lot left out that everyone at the time in-the-know new was being developed and tested. But because of world politics and powers, we never get anything of substance.
Most scientists believe that discoveries are at least 10 years behind because of govt black-outs on research. I dunno if that is true, but we are still finding out today discoveries, developments, and projects from 50 years ago because of classification.

A soccer ball originally packed onto space shuttle Challenger in 1986 is now orbiting the Earth on board the International Space Station, 31 years later.

Just a random thought after watching some Star Trek last night....There is no atmosphere is space, so sound pressure and waves do not exist. There is no oxygen or other flammable gasses as such. Therefore, there are no explosions in space like in movies. Or any sound that would be made for anything.

Good to see that kids are still playing with Newtons first law of motion:

Right? I don't believe this particular gentleman has an understanding of these laws. Though, he does now understand that he was moving until he was stopped by the force of gravity and concrete.0 -

Just saw this thread....kinkyslinky16 wrote: »kinkyslinky16 wrote: »kinkyslinky16 wrote: »Google Sky app does the same thing.. it's super awesome
That's cool.
The program I was talking about actually shows you what the sky looks like from wherever you are standing at what ever time you choose. Then it tells you about the consolations, paths, and celestial happenings. For example, if I want to know what that bright star is, or if it's a planet, then I can easily look up what I'm looking at.
Yes, Google Sky does the same.. you aim your phone or tablet at whatever you are looking at and it tells you nearby constellations, planets, everything. I love it!! If you haven't tried it, download it and see if you like it.
Ahhhhhh. One of those phone thingys.
I'm sure there's a desktop version of Google Sky Map for old folks.
There's some incredibly awesome pictures on this thread! I'll have to Google for that "Old Folks Google Sky Map"
Oh and..
