I was inclined to poo-poo this paper but it does make an interesting observation. Venus has a crushingly dense atmosphere now (mostly CO2) but it is 3.5% Nitrogen. The authors point out that the weight of Venus's Nitrogen is actually comparable to the Earth's (10^19 kg). The field of astrobiology runs off the rails in its endless focus on carbon and water when what you also need is nitrogen (and reduced at that). Since the sun was once cooler and Venus was once wetter there is good reason to investigate the possibility that conditions were once life favorable. Too bad it is most assuredly dead now.
Pick up the phone. The UC system is a government (cf. political) entity that relies on federal largesse. After her phone call a behind the scenes scramble would secure these particular jobs. It would not solve the problem in general of course but a Senators influence is formidable.
Self interest. My teenage horde of comics, scfi fi pulps and ancien Hardy Boys novels ain't selling on Ebay because all the potential customers torrent the entire history of Superman off piratebay thus leaving my carefully bagged collection worthless...with transferable digital copies you create a LEGAL aftermarket of say all of the X-men series for 0.5 cents.
I have accumulated a modest Apple music "collection" -- giftcards.
I have an old firewire iPod and an old laptop. Old G4 laptop started to give up the ghost, I want/went to authorize a G4 iMac I got (to use as a music server it's cute).
iMac iTunes can't phone home to authorize the music library I legally purchased. Not stupid, it's no longer safe to browse the internet with this old thing but it can't even update it's iTunes to allow this basic function.
I am well aware of other means to get my Apple music into another format but it is annoying.
NYC uses 60 GWh per year. This is a unit of energy per year. This is 2.16X10^17 J/year This works out to 6.84X10^9 J/s A J/s is known as a Watt which is a unit of power. This solar thermal plant is a 140 MW plant. It is well known that the sun does not always shine... This is 140X10^6 W. Were this a constant level of power one would need... # plants = (6.84X10^9 W)/(140X10^6 W / plant) = 48 plants.
Your main error is failing to recognize a ridiculous number (120,000 plants) when you took the time to post your opinion on this forum. You get an F.
I recently was planning to digitize a number of cassette recordings -- radio broadcasts from the early 80's -- and well the horror. Hiss. And these were high quality cassettes. As with the commercial cassettes easily the worst format in the century of recorded sound -- I think wax cylinders and piano rolls hold up better.
There are many stories of film crews waiting around all day for that perfect sunset glow. Much easier to hire one guy to fix it in post. The parent might have mentioned that the Dogme 95 movement was way ahead of the game here and that although I would love to see an Avengers sequel directed by Lars van Trier it ain't never gonna happen.
I had never heard of MusicBrainz (or Discogs) before...I use Wikipedia and Ebay....shy away from Amazon. The visual aspect of Discogs is a big plus...browsing through a stack of albums is a dead art...and having a marketplace next to reviews and discussion groups seems a good way to find new music (in my case new means old...very very old.)
This movie sucked, was worse than the prequels and it is shameful that it got made in the first place. I am surprised critical opinion did not pan it outright. Boy was I fooled. Star Wars as a franchise though may have some merit. The fans have more imagination than the makers. Please go on being a true believer if it makes you happy.
Remember it's only mutations to the germline (eggs and sperm) that propagate so the developmental buildup of damage is comparatively silent in an evolutionary sense unless it stops you from passing on your genes. Cancer sucks, in the modern world the old folks can still contribute but the alarm clock for the reaper was set during the stone age.
Yep. But cancer is complex, not all die from it, and you have to assess it tissue by tissue. The male probability of prostate cancer goes with your age but most succumb of something else.
I work in the Cancer field here's my take home take. The Individual probability for Cancer risk is in three parts. 1/3 Genetics: Beyond your control, a complex interplay of genes can lead to cancer. 1/3: Environment: Within your control there is a known influence of diet, chemicals, radiation, pollution etc. Lifestyle in other words can impact this component. 1/3 Random Chance: Billions of cell divisions occur to in our lives. The protein machinery that makes this happen has incredible fidelity but mistakes inevitably occur and this DNA damage can cause cancer, usually later in life. There is no lifestyle choice that an individual can make to prevent this damage from occurring. I would also lump into random chance the random inflammatory insults that occur over a lifetime -- a cold at a young age that damaged a subset of lung tissue that mutated the p53 gene giving rise to etc. The linked paper/story reveals a raging controversy between constituencies for each part of the cancer risk pie. The losers are the patients/public who are misled by either an indifference to risk aversion or a single minded overestimate of the benefits of lifestyle. Its all three.
Space exploration is for the patient. Science fiction is for phonies. The popular science fiction (always endemic on this board) with its fantasy physics always ignores immense distances, energies, time, politics and money. Most importantly money. During the last 43 years we have probed the entire solar system and are currently roving the sands of Mars as we peck away at our keyboards at a safe distance and for costs that do not over burden society. Space exploration is a constant source of scientific achievement and with advanced directives and equipment (Kepler, Webb) we are going to explore the galaxy in the comfort of our sofas without breaking the bank Because that's the trick, our robotics can pave the way for us because Space is a harsh place. Now the next step, and it could take 50 years, is the when we land a lathe and a robot to operate it on the Moon. Soon after there will be an image of a dome and behind it the earth and in the dome there will be a bunch of green leafy things curling up from the lunar soil to reach for the sun. And then things will probably go a lot faster.
This dovetails on an idea I've wondered about...how good are the rovers from Apollo 15 16 and 17? Maybe the killer app for this humanoid is to land her by the 70s vintage cars we left there with some spare rechargeable batteries, a set of tools and a portable solar array. Have Valkyrie fire up the juice on the drive train and then set off with the goal to make tracks across the entire lunar equator. I guess the question is, did we leave the keys in the ignition?
I hate laptops...I work in specific places. I tote my Mac Mini to and fro and plug it into the prepositioned mouse/keyboard/screen combo. It runs Linux and Windows.
Point well made...and the mix of tele-operate and autonomy is the proper unsurpassed role for manned missions. Capsules and rockets are 60s science. Organization will conquer the solar system. More money for NASA robotics.

Were you ever able to leverage this learning experience to get a job?
Maybe we should all adjust and get up at noon.
