An outstanding entry in your arxiv paper download

Many wonderful treasures are saved in the Harvard plates, but the reality is that the current generation of astronomers are mostly unaware of their existence. J. Grindlay has started and lead the work to completely digitize all ≈500,000 plates (Grindlay et al. 2012; Tang et al. 2013). His program is called Digital Access to a Sky Century @ Harvard (DASCH) . The products are top-quality digitization for each plate (plus the envelope, plate markings, and logbook entry), plus fully-calibrated magnitudes for each stellar image on the plate. Currently, DASCH has completed only ≈15% of the Harvard archives, and this includes all the plates covering the original Cygnus/Lyra Kepler field.

Re: Desparate or Greedy

The Nazi used that kind of unstable highly dangerous rocket fuel because they were desperate.

We had this stupid shit in the last thread. Fuck off, troll, die under a bridge.

For reference: Wehrmacht used Alcohol (from potatoes) + LOX. Here we are using Kero + LOX. None of these is "unstable".

Re: Why not a catcher's mitt?

The remaining fuel sloshing around in the tanks might be a problem with this manoeuver worthy of a dolphin. And how do you get the gravity center far below buoyancy center so that the engines STAY in the aire?

The problem with going into seawater is the seawater. Don't get it into the engines.

Retrieving the rocket? You will have to pull the upturned rocket out and basically cut of the maybe-not-empty tank section while the house-sized stage is hanging off a crane. In open seas. Not fun.

> flexible webbing to catch it as it falls a short distance

The barge would have to be very large, the webbing very tough and able to withstand fire from above and the 1st stage able to sustain sudden lateral compression (plus major forces in a few points along the webbing lines) as it settles and topples

> docking clamp system with room for error

Again, a very large docking system would be needed, and the likelyhood of wrecking the first stage and the docking system both would be very high. An expensive loss..

Keep it simple! If you have a rocket engine on the object-to-land, use it!

You can't see further than the moment when the universe was opaque and mixing the light quite tremendously.

This is what the CMB is: the light that started free-traveling as the universe became transparent, a few million years after GRIDFIRE EVERYHWERE (aka Big Bang)

Re: 3,8 billion years ago is a long time ago

The other possibility is that it was just beam focused towards us, same as with gamma-ray bursts which apparently are not omnidirectional because that would imply ludicrous amounts of wattage; they are just doing a lighthouse impressions.

Re: No H or He?

it's 3.8 billion light years away, meaning it's also 3.8 billion years old

The part that we see is 3.8 billion years young than whatever is "now", or maybe a little bit less seeing how space expansion is accelerating, not sure about that.

the explosion occurred 3.8 billion light years away

In a rescaled picture, if Andromeda Galaxy is 2.5 mm away, that would be a whooping 3.8m away.

There is a LOT of Galaxies and Galaxy Filaments between us and that. Definitely a challenge for any Space Knights looking for a Space Holy Grail.

If Clarke were right, these things would be unobservable because the expanding bubble of vacuum decaying to a lower-energy state (thus liberating free energy while changing subatomic physics to something totally unknown) will be following in the wake of of the expanding bubble of light at a picosecond interval. You will never even know what popped your Standard Model.

Re: He/O

This has been discussed at lenth (and competent) in the comments on the article announcing the Two-Tim-spacewalk a couple of days ago.

Checking there.

So it seems to be about reducing suit stiffness due to high internal pressure.

This means you have to increase the oxygen content in breathable air to keep partial pressure of Oxygen constant.

Helium is used to replace Nitrogen in high-pressure environments because Nitrogen has toxic effects on the nervous system at high pressures. So this is not useful here. Using Helium also increases the problem of outgassing ("the bends") when pressure falls, so this is even less useful.

So this is all about a slow decompression to get to spacesuit-agreeable low-pressure while avoiding outgassing while keeping partial pressure of oxygen constant.

Maybe one should switch to Arthur C. Clarke rigid suits...

Astronauts have to purge nitrogen from their blood for hours by huffing pure oxygen before suiting up to avoid getting the bends

Is the pressure of the suits significantly lower than the one in the ISS? shouldn't the astronauts also decompress to suit pressure while living in the pure oxygen atmosphere (otherwise they will get oxygen poisoning)? Ho about using He/O mixtures then?

Re: The human pilots just do the easy bits...

The IT industry is on an interesting cusp as people who joined the industry in the still-pioneering 1960/70s are now retiring. With them goes a lot of wide and deep knowledge about what the evolved technology does - and why.

At first I thought "what a crock". But then I looked around me and found that not many IT people around me (and even at uni) are/were interested in system design, engineering basics, information processing basics, history of computing and the classics from the 80s or even the mathematics that you actually need to think about the systems in front of you. The assumption seems to be that somebody else does the hard job and good stuff appears from an information-generating magical font. We'll just overpromise and rake in money while outsourcing coding to offshore fly-by-night outfits. A recipe for disaster.

Re: Regular releases

1) That's not how it works

2) There is confusion between agile delivery of the scrum sort and "dev ops"

3) This is not how agile is supposed to be done; it'a about having feeback on a pipeline of short actions (as opposed to a long stovepipe of large actions); it is not about ramming half-processed stuff into operations at fixed intervals. Plus building the artifacts that keep the mutating product in the "requirements funnel".

Nautilus is really an amazing magazine. Every paper issue is a work of art in itself and there are no addies. I don't know how they do it.

I recently came across a short biography of Walter Pitts, which I had only so far seen mentioned in a textbook on Neural Networks and maybe in a book by Marvin Minsky.

Also, this review reads like it has been written by "jake", how come?

How about some Rodney Brooks instead? I haven't been following "Nouvelle AI" (described in "Cambrian Intelligence") during the last decade (too much webshit filling all available brainslots but I have been getting back into logic programming a bit ... Answer Set Programming sounds really sweetuseful). I remember reading research on "Cog" has been discontinued and Brooks & Company are now selling a sturdy, marketable single-arm manipulator robot.

Re: Do androids wet dream of electric sheep?

They were wet-ware with wipe-dates, no silicon involved.

This is correct, but of course testing for this special makeup physically would have been easy-peasy. A drop of blood and check the DNA. Done! (Like the Gaius Baltar test which was not handled all to well in BSG at all).

The Philip K Dick novel's androids appear to have been a mix of robotic and organic bits.

Not that I know. They were, however, devoid of natural human reactions and empathy (psychopathic) and killing them was considered taking out the trash. Even Rachel was the most horribly sadistic and manipulative thing.

Re: They land back to earh requires an ungodly amount of fuel

TFW you remember the first time your read about "Delta-v" in the novelization of "2001 - A Space Odyssey" back in the 70s.

"At the moment my closest approach is sixty miles; it will increase to about a hundred as Japetus rotates beneath me, then drop back to zero. I'll pass directly over the thing in thirty days – but that's too long to wait, and then it will be in darkness, anyway.

"Even now, it's only in sight for a few minutes before it falls below the horizon again. It's damn frustrating – I can't make any serious observations.

"So I'd like your approval of this plan. The space pods have ample delta vee for a touchdown and a return to the ship. I want to go extravehicular and make a close survey of the object. If it appears safe, I'll land beside it – or even on top of it.

"The ship will still be above my horizon while I'm going down, so I won't be out of touch for more than ninety minutes.

'Tm convinced that this is the only thing to do. I've come a billion miles – I don't want to be stopped by the last sixty."
