I agree with you that you cannot recreate the real stress of a cross wind landing with important people on board with a simulator, and nav is probably the best thing you can learn with simulator (I had one hours of flight sim booked on a simulator). This being said, having done 10 hours of training and land / takeoff around 30 times (for personal reason I could not finish my license), my instructor was impressed on my first landing the way I had the proper angle and speed at base and final. I think if you 'play' hundred or thousand hours on a good simulator, you get a pretty good feeling of the limits of the plane, when it is the proper time to turn, adjust throttle, feel the concept of aerodynamics in regards to the stall, and get good instincts to what to do to achieve a new position.
QWERTY and AZERTY have been created to minimize the possible jam of dactylo, around 1872, not to be fast but to prevent jamming. If letters were presented in alphabetical order, we would have "ST" for example offen used and would create dactily jam. Now that dactylo era is over, some alternatives exists like "Dvorak Bépo".
I did drink some scotch, but I hope moderators will raise you, since what you just said is absolutly right. I mean, everything have a causality, and if this lead to not put in prison people that does did offence to what we consider ok, everything will find a causality to people behavior and this will lead total collapse. We cannot accept "as superior knowledge people" the behaviour of inferior one because they did have a physical excuse or pre-adult bad learning experience.
I'll change subject a little bit, but since we are overpopulated, why not sent to forced labor for life everything that is now > 2 years in prison offence, and never include excuses for lower sentences?
"- Finally the point that wake me up to the possibility global warming is maybe political / taxation propaganda : ALL other planets got temperature increase.
What?"
Since you are really defending antropogenic global warming, you surely know that all other measure got temperature increase, as planet earth, do you?
In fact, I have some problems, but let's have some here :
- Artic ice cap, as antartic ice cap, melt and reform each year : something I didn't knew before doing my own research. Artic ice cap size reduce something like 5% per year in the last 20-30 years and the antartic ice cap size is GROWING, slower but growing each year. - The growth in temperature for more than a century is less than a celcius degree (0.76 if I remember well). Half of this increase happen if I well remember before WWII. - In recent years there have been no increase in temperature, even if co2 incresed - Temperature measure are often done in inner city, where temperature is effectively slighthly greater - Finally the point that wake me up to the possibility global warming is maybe political / taxation propaganda : ALL other planets got temperature increase.
So yes maybe a majority of climatologist could agree that global warming got a human original, but I'm not buying that. I could agree maybe for a point around 20% of global warming is human origin, but absolutly no more than that.
This being said, I'm very ecologic and I make a distinction between pollution and global warming.
This story really make me think that handwritting *will* one day not be teached. We have to assume that one day when full portable computer will be around 20$, there will be absolutly no need to ever try to write anything, except small note where anyone can write in it's own cursive or simply full letters. Speech recognition with search capability would also nearly remove the need to ever write something.
For my part, I've been using computer since 7 yo and I'm now 34, and I can tell you that I'm writing probably 4-5 times faster with a keyboard than with a pencil, and it's 10 times more easy to re-read myself (this is when I'm able read back what I've written, but that's another story).
If you think that 9/11 was an inside job (as most people that seriously analyse all the aspect of the 9/11 facts, as most of the close familly of the lost ones), then patriot acts and all other mesure to try to keep us far from terrorist is only a mirage, a way to get more control over american citizen.
To answer your question, I seriously think a pilot cannot estimate correctly his speed at this altitude. BUT, in regards with the power sent to the engine (thrust), you know thrusts must not be at maximum since you will overspeed, nor too little or you will stall. If you take flight simulator for example, putting thrust at 30% of maximum thrust will give you a decent speed. A professional pilot will be able to roughly guess his speed from power sent to engines, if his altitude is stable. For that, if your altitude gives you something very imprecise or simply wrong, you simply need to stay nose on the horizon (in night at this altitude you would normally be able to see stars and horizon, or you simply keep your eyes on the gyroscope in the cockpit that give plane situation in space. There is some possibility you will slowly climb or going down, but from 35000 feets you have time to make emergency calls. So with many alerts of false speed and false altitude, an human override reaction would be in my opinion simply to put thrust at something known for a decent speed, and keep nose at horizon. Having a gps on board for altitude (even a portable one) would give enough precision to keep going up to europe. Knowing roughly wind speed from air traffic controler for a specific altitude, and speed given from a gps, pilot have enough information to stay in a safe zone (speed/altitude) to be able to finish his route to europe and/or goes back to bresil. The flight could have taken twice the normal time, but alive maybe...
In my opinion, pitot tube slowly get stuck with ice, autopilot push thruster more and more to get the right indicated speed, and the plane overspeed. Probably both pilots didn't disengage autopilot since they were in turbulence and the overspeed vibration was tought as normal turbulence. Normal behaviour is, especially at night, to beleive your instruments. Then overspeed comes and the wings breaks or some part of the place breaks and the plane went into a fatal 35000 feet plunge.
I wonder if overspeed near sound speed would make the front window to explode first, explaining no emergency calls.
It's not because it's used since 30 years+ that TCP is so great. Does VHS was better than Beta?
Making a home made TCP over UDP isn't especially complicated ; especially when you have no obligation to get packets in the right order, and that you can retry if you get a missed packet.
I think the best of both world would be to use a FTP like scheme : one tcp channel to do control, and UDP packets for file content. If the TCP get throttled, this is not a big deal since there will be not so much data on it.
This antimatter creation could lead to a bomb device capable of very big destruction, without radioactive creation. This would make possible attack on countries that US would not have attack considering the country spoilage due to radiations.
Yes they didn't create a lot of antimatter, but you can do that all day long until you have a mass enough to create the bomb. For conceiling, magnetic field should be enough.
And there is possibility of using this into munitions, like a little magnetic sphere holding the antimatter, when crushed into something simply explode.
In fact I'm totally against war. But if war has to be, this tool can be cool. You can put a remote grenade inside of this little gadget, and if there is people where it lands, you detonate it. So it's maybe a little expensive grenade, but can be pretty usefull in some situation. The cool part is that you can reuse it in case it lands where nobody was.
But hey, I'm against war.
There is a ton of places, like any northern places in Canada, where electricity is cheap and is really cool nearly all year long. I could think about Quebec province, in Canada. Electricity is approximatly 5 cents (canadian) per kw.h (like 4 cents US$) and it would cost nothing to cool down as much server as you want.
Maybe some company already have such datacenters, but I could think about some google / microsoft datacenter going to canada, to save on electricity bills and cooling.
Nuclear can scrap electronic inside the robot. One easy plan (with budget) would be to put an nuclear "heater" / electrical generator at the base (where the robot lands) and let the robot hybernate / regenerate at the base, for winter.
Next step would be a repair shop that could be remotly controlled, to do some job robots cannot do alone. This would give a lot more lifespan to those robots.
But even with that, if the batteries inside the robot have a lifespan, you cannot repair / recharge them indefinitely.
I was exactly asking myself a similar question. My main concern was if the tractor has a gravitational impact on the asteroid, the same apply for the asteroid to the tractor, and they should collide. So the tractor has to repulse itself from the asteroid. Probably if the tractor is far enough from the asteroid, any propulsor would eject matter behind the asteroid, so the force used to keep away from the asteroid would not repulse back the asteroid on the path it should not go. But, why this energy is lower than the energy that could be used if the tractor is landed on the opposite side and "pushed" the asteroid away, I really don't know. Probably the fact that landing such tractor is a lot more risky than simply being on a parallel path.

I think I want to re-install flight simulator!!!

One of the best analogy for P=NP I've heard about, thanks for sharing.
In case USA need to detain someone more than 72 hours, they send them in Guantanamo and this hack allow them to respect the rules of the constitution.

It's exactly the same thing that happens on wikipedia with Jean-Pierre Petit, astrophysicist.
Doing as Fox news is already doing for years, they will slowly learn how to control the masses with television. Nice work Iran.

I think some people in USA doesn't have 3 meals per day, am I wrong? So what the heck US soldiers are doing in Irak?
Didn't know we were in april yet...
Excuse me, but QC is for Quebec calvince.
This project is simply another... Vaporware!

We have a scientist, named "Jean-Pierre Petit" (see wikipedia). He predicts some of galaxy configuration. Please read his paper, it's interesting.

I don't get it. Creationists are wrong? I was sure dinosaurs were there to test our faith.

Very disturbing indeed!
