I find it to be pretty awful, really. Tolkien just prattles on and on and on and on about a bunch of hyperbolic shit. Every location and creature is described in extreme detail only to be outdone by the next that's more fantastical, more evil, more ancient, a taller mountain inside a deeper pit, etc.. And here's a fucking song for no reason. And Hobbit food? It's like the scene in Forest Gump describing different types of shrimp, but it's not funny, nor is it interesting. It's just filler.
Some nerds call this shit "world building". I call it Tolkien loving the smell of his own farts.
As I type this the above post is rated "Troll". That seems remarkably appropriate.
Aluminum has no such point - flexing it will always cause it to weaken (which is why it was stupid to make Curiosity's wheels out of aluminum).
Reading the article and consulting NASA information about the Curiosity mission does not support the assertion that the wheel design was in any way "stupid".
According to the article you link to the (many) components of Curiosity were not tested to destruction but were tested a maximum of three times the expected mission life without failing. Curiosity was never intended to last "forever" but to last for its two year mission life which involved an 8 km trip to Aeolis Mons, its mission target. With a three-fold mission life testing program this suggests that the rover could be expected to last up to 6 years and travel 24 km before failures would likely end the mission, but anything over the original mission specification is gravy. Curiosity has now traveled 17.5 km.
Again, according to the article, what they have observed is cracks in two treads in one wheel. Test data indicates that when there are three cracked treads the wheel is at 60% of its service life. Currently there are only two, so it is at less than 60% of its service life. But let us suppose that it is at 60%, then it should be good for 29.2 km, i.e. for another 12 km, which is over three times the planned mission. But since it is only two treads, it should be more than that. What's more this is only in one wheel so far, and Curiosity can travel on five good wheels, so the service life limitation from wheel wear is likely to be quite substantially more than another 12 km. By then lots of other components will have exceeded their 3-fold mission life testing and be candidates for failure.
In short the wheels seem more than adequately spec'd and tested for the mission. It is unlikely that they will end up the cause of mission end, which in any case will be well more than three times the original planned mission. Putting 100 km wheels on Curiosity (for example) would simply have driven up cost, reduced the weight budget for some other items, all without meaningfully extending the mission potential life.
Again this supports exactly what I said. It was not the structure of Grenfell Tower that burned. It was a decorative outside "furnishing" added to the building.
Perusing the document, it seems to support exactly what I said. I specifically mentioned the fire encapsulation requirement that is used in modern wood frame structures citing gypsum board (though other solutions exist.
Wood can be grown and harvested sustainably on tree farms where generation after generation of trees selected for structural properties and rapid growth are cultivated. Any such "green" inspired building program should/would ensure that all the timber used comes from such sources. And so yes, building permanent structures out of wood does lock up CO2 as long as the structures stand - whereas CO2 released in the production of concrete is in the air for centuries.
The actual material used for framing a structure has nothing to do with the fire safety (or lack of same) in an inhabited structure. Metal and concrete framed structures are no safer on that count than wood. The fire hazard that threatens life is entirely due to the furnishings and utilities inside the structure. By the time a frame of wood frame building starts to burn the interior is already destroyed, and the inhabitants have either escaped or are dead. Note that modern construction techniques using fire proof gypsum board that isolates the structure from the interior (gypsum does not burn and actually absorbs energy as it decomposes).
Wood is a pretty remarkable material. It is in fact an advanced composite material produced by natural nano-factories. It compares favorably with far more expensive synthetic composites, and beats them all in cost. Used properly (taking advantage of the anisotropic properties of wood beams) a good wood beam comes with a factor of 3 in stiffness/weight ratio of the best performance ofunidirectional carbon fiber epoxy composite, and beats structural steel. Sitka spruce is used in the upper stage of Trident II SLBM missile since it had the best properties for the role, over all other candidates.
the information remaining in the collection that has not been released publicly includes materials that are protected by copyright; sensitive such that their release would directly damage efforts to keep the nation secure; pornography;...
I am incensed! I believe that it is important to posterity to be able to comment authoritatively about exactly what kind of pornography Osama bin Laden was into!
Or we can just accept a declined standard of living.
Just like after the first industrial revolution ?
I am pretty sure you think you are sarcastically "showing up" the previous poster - but, yes, exactly like the First Industrial Revolution.
The average per capita GDP went up (on average 1.7% a year) but the distribution of income got much more uneven, and the living conditions actually deteriorated for a large share of the population that made up the new working class and pauperism (being destitute) sky rocketed. There is excellent physical documentation of the declining standard of living among working class. Adult heights declined, lives shortened, the portion of recruits unfit for military service shot up. The urban slums and work houses of Dickens time were a product of the FIR.
I hope there comes a day when there are no more overpaid actors. Let THOSE jobs go to computers! We aren't there yet but this is a step in the right direction.
Even when computers can generate photo-realistic people that can move like real people you are still going to have actors.
Why?
Because the job of actors is not to simply be "photo-realistic people that can move like real people" (we call those people "models"), their job is to act. They bring life and nuance to the characters they portray. Consider Andy Serkis's Gollum. He is as realistic as he needs to be, but he would not exist as a convincing character without Serkis's motion capture acting.
Computers do not act. Neither do animators. Audiences can tell the difference.
If (when) we can overcome the uncanny valley it will break new ground for creating animated characters that are powered by human actors. But the human actors will still be there.
There was an indictment of some people who worked on Trump's campaign-- most notably his former campaign manager. But the indictment was for stuff that they did before that-- 2008 to 2014, to be specific.
I followed the link you posted and found this (which is unedited):
But the revelations contained in the Papadopolous court filing are less easily dismissed.
Papadopoulos learned in early March 2016 that he would be an adviser to the Trump campaign on foreign policy, and that one of the campaign’s principal goals was to improve U.S.-Russian relations.
It was after joining the campaign that he cultivated relationships he would try to use to broker an overseas meeting between the Trump campaign and Russian government officials. According to the court filing, the proposed trip never took place.
But Papadopolous’ repeated outreach efforts are sure to raise more questions of collusion, particularly in light of the fact that Donald Trump Jr. accepted a meeting during the campaign that was predicated on the promise that a "Russian government attorney" would deliver damaging information to him about his father’s Democratic opponent as part of the Kremlin’s effort to tip the scales in Trump’s favor.
Papadopoulos’ guilty plea is the result of a negotiated resolution between the defendant and the Justice Department, said Andrew D. Leipold, law professor at University of Illinois College of Law.
So Papadopoulos crimes, to which has confessed and pled guilty, are entirely due to his work on the campaign.
Although I respect your attempt to back into the V_infinity figure for A/2017 U1 using only the information presented in a news article and guesses about the current distance, we have a GIGO situation here. You are way off.
The actual value of V_infinity (velocity excess after getting arbitrarily far from the Sun) is 26 km/sec, and astonishingly high number. This is a kinetic energy 2.6 times higher per unit mass than we have ever imparted to any object with rocket technology (and this New Horizons).
Or we could conclude that it was so close to being exactly parabolic that our measurements weren't precise enough to determine which side of eccentricity 1 it falls on. This isn't that unusual (especially with older, less precise observations).
Your suspicion should have consulted some actual data.
This is the most hyperbolic orbit ever observed. A parabola has eccentricity of 1 (exactly). In natural objects it really divides orbits into elliptical ones (less than 1) and hyperbolic ones (more than 1) though they could be so close to 1 that measurement error cannot distinguish them.
A/2017 U1 has an eccentricity of 1.1922 ± 0.00268.
This an eccentricity excess about four times larger than the next highest observation (comet C/1980 E1, with an eccentricity of 1.057). This represents a hyperbolic velocity excess of 26 km/sec. No known process could add this much velocity to an object that started as being gravitationally bound to the Sun. For example the fastest object we have ever boosted with rockets (i.e. not using additional gravitational slingshot maneuvers)
was New Horizons which only had a velocity of 16 km/sec. And since kinetic energy goes up with the square of velocity this object has 2.6 times as much kinetic energy per kilogram as the fastest, most energetic probe.
Being a real nerd I only RPN calculators - I hate algebraic ones - and usually download an HP-11 emulation for familiarity. Plus I need the more advanced math functions.
This difficulty was noticed by Olders who however was not able to suggest any solution. The discovery of the recession of the nebulae by Hubble led to the abandonment of static models in favour of ones which were expanding."

Singapore's road system in entirely built out. All of the island is urbanized. And the effective capacity of a finite, fixed capacity road system is also finite and fixed. They have decided that they have now reached capacity.
Other urbanized islands do this. The number of vehicles in Avalon, Catalina Island is also fixed.
The ISS requires 7,000 kg of fuel for reboosting and attitude control each year. The experimental Ad Astra VF-200 200 kW VASIMR electromagnetic thruster has been under consideration for providing his capability, and would consume 300 kg of argon a year. So resupply would still be needed, just not as much.
I suspect the maintenance is more than just fuel. The heat/cool, air, seals, power all require machinery that breaks so there is a constant need of attention. I used to have a sailboat, it too kept dissolving even if not used.
And you suspect rightly. The workload of maintaining the ISS is almost two full time people. It could not be left unoccupied for long and expect its systems to remain intact and functioning - though there would be less stress on the system with no one on board. Some type of hard shut-down procedure to mothball it would be required, and probably require spending more money on special equipment to do it. And then reactivating it later would be an untried operation.
And then there will be frequent reboosting cost, which is currently done about once a month.
Thanks for calling attention to this site. Never knew it existed.
When I look at the map I see an elliptical zone that is 19 degrees tall and twice that in length (that is too say, about 2000 km by 4000 km) in which there is exactly one vessel (a fishing vessel).
A bullseye in this zone would be at least 1000 km from any other vessels, except for that one fishing boat, and they could miss him by at least 500 km.
I'm curious the strategic use of bombers on 24 hour standby, when there are enough ICBMs, including those in nuclear subs which are likely really, really close to North Korea already, to totally decimate that country...
I, for one, really like the idea of nuclear deterrent force that is slow and can be recalled. I'm sure most of us here can imagine reasons why this would Make A Great Attack plan.
BTW, according to the article no decision to make actually start 24 hour alert has been made. They are doing this "just in case". But there is no explanation of where the decision to start these preparation was initiated. I checked the Barksdale AFB news site which mentions the same visit by the general five days ago, but there is absolutely no mention in the past year of any alert preparations, much less plans.
