The best correlation of student success is parental interest in their kids education. I come from immigrant family were this was a factor. I and my brothers all received at least one ivy league degree. I've seen poor immigrants from east Europe and Asia do well even when the family did not have a lot of money. Unfortunately the two largest minority groups in the USA do not have lots of family interest in education. They dont do as well even when their schools are well funded.
This is the first year they are "rationed" with a lottery, because they having been reaching the BLM quotas the last two years. But no one seems to be able to get one. The scalper community went after them.
Monday is the half century since John Glenn orbited the Earth. Fortunately John has Betty White genes and still with us after long career in public service. The sad thing is that John's career may bookend the US manned space program. He saw both the beginning and probably it end for along while.
The gist I got from Robert Hazen's course on the Origin of Life is that the metabolic citric cycle and protein polymerization does not require enzymes in high pressure and in certain mineral substrates. Otherwise you have the chicken-egg problem of how to elvolve these special enzyme proteins first. Dr. Hazen generated many of these results in the lab.
When it ended US manned rocket launches, i.e. killing the shuttle replacement. The shuttle was the public face of NASA. The average Joe is not highly interested or informed about egghead space probes. The best replacement for the shuttlle- Dragon- is slipping badly in schedule. Its software was determined not safe enough by NASA standards, and sent back for reworking. killing the rest of NASA is just a postscript.
The evidence is pretty good for shorter Arctic winters and rapid Greenland melting. The Antarctic is less clear with some areas staying very cold and others melting. I've heard Susan Solomon of ozone-hole fame discuss the Antarctic situation a few times. The so-called "third pole" the Himalayas, appears to be equally ambiguous. that is currently the most important pole, supplying a third of the worlds population with water.
Khan uses the oldest educational technique in the book- the demonstration lecture. Its just packaged better. First someone who clearly explains it. Second in a right-length chunk of a few minutes, not a forced 60 minutes. And on demand, anywhere, not on a schedule at a certain location. And almost free, after it is done the first couple of times.
People have been trying a half century to properly use television and computers in education. This seems to be one of the better results.
Star Trek is about 1960s culture transposed into a hypothetical future. In the 1960s the US was at the peak of its imperial power. Social mores were opening up due to this-and-that "liberation". Computers were starting to affect daily life.
1980s was a condrunum to me. MSFT came of age then, but they originated in the 1970s PC boom. PC clones, workstations, supercomputers, A.I. computing, pen computing were 80s stuff, but not mega-hits like these others. You could argue Dell started in dorm room and became a billionaire, but his stuff more of a new business model than a revolutionary technology.
Then too I place Google with the 1990s web guys even though they had their huge IPO in the mid-2000s.
Social computing originated in the 2000s (or earlier). But the big IPOs are now.
As numerous as Foxcon's flaws are, they pale in comparison to the more numerous non-name contractors. The non-names break many more labor laws, pollution and safety regulations, and stiff wages. They bribe or have connections with the petty bureaucrats. They've been known to pack up machines on off-day Sunday and disappear leaving workers unpaid and unemployed. Everyone knows this is going on and make movies and write books about it. I've seen several. The workers know this a crave the established contractors. A new farm boy will do a couple stints at a no name and they qualify for a Foxcon. It takes time for the legal system and societal expectations to take firm root.
I probably attend a half dozen a month: author talks, museum talks, computer user groups etc. The difference is they are usually one of a kind. Its a lot different have them forced down your through, 12 a week (3x times four classes) for 15 weeks in a row. i find I learn best by a whole variety of media: lectures, tv, internet, books, active problems, etc.
15% of us die of accidents, violence or suicide in our 80 year lifespans. Eliminating all natural causes of death would only extend our lives so much, unless we practiced a culture of extreme safety. (This has been the theme of many scifi stories about immortals.)
Some trees may essentially immortal, but suffer from weather or animal trauma etc. Almost nothing is alive older than 10K years.
All R&D agencies and funding consolidated in one government department. They said "No Way!". They like the current system because they can apply for grants to multiple sources with the hope at least one succeeds. A Dept of Science would all your eggs in one basket.
With a single grant source, administrative costs would be greatly reduced at both ends. Current government agencies would hate this too because each one wants to be in control of its own R&D empire.
(1) Biosphere: (medium) abundance of plants and peat deposits, waxing and waning with ice ages. Changes over 10,000s years.
(2) Plate tectonics: (long) carbon capture in limestone, release from subduction volcanoes, possible permanent burial in subduction. Plates change speed, length of subduction zones over 100,000s to millions of years. Limestone contains 100 times the carbon in the biosphere and draining out the atmosphere over 100s of millions of years.
(3) Human: (short) deforestation, extraction and combustion of hydrocarbons. Just centuries. Deforestation will reach steady state soon like in North America and Europe. We are probably midway through 300-400 year "hydrocarbon age" of consuming all the extractable petroleum, natural gas and coal.
The competing Gaia hypothesis says life may do something to counteract this. Possible a combination of changing the atmosphere to repel radiation and new biochemistry to live at 100C.
Correct. But Peter adds the Earth is cooling off and plate tectonics will slow down too. It looks like PT has been rpetty active for the past billion years. Earlier evidence is more sketchy.

We live about 1000 moons (82 years).

Your spin does not bring back a prematurely terminated shuttle program nor improve the anemic private sector.

but that may drive away the younger crowd

The recruiters way outnumber the people looking for jobs there. At least they buy pizza and the first round of drinks afterwards.
In the past couple years this meetup has become indistinguishable from the Java User Group. And its spawned an Android, html5, and design meetups.
he can was football and TV on the other side while listening to you.

The chip guys in the 1960s.
The PC guys in the 1970s.
The web guys in the 1990s.
The social computing guys in the 2010s.
Looked good on my resume! BR Probably in some braindead job re somewhere.

They could cone-off a space until you pay them off.
There are few around here tha say the number of empty spaces on a given level. They may say 20 and nothing is open. Broken sensors.
