Mathematician John Nash, wife killed in car crash

http://edition.cnn.com/2015/05/24/us/feat-john-nash-wife-killed/index.html

Such a sad tragedy..

If one considers that the city of Dresden was the target of about 4000 tons of incendiary bombs, and that the estimates for deaths from that one bombing, range from a low of 25000, to 100000 or a possible high of several hundred thousand ( not likely ) casualties, the two atomic bombs each killed from 4 times as many to about the same number of people.

So what is different..

That they were Japanese ?

Japanese had their own Dresden, disgusting and senseless bombing of Tokyo with firebombs.

http://en.wikipedia.org/wiki/Bombing_of_Tokyo

Either Hiroshima, Nagasaki, Tokyo and Dresden, are all examples of war crimes, that nobody was arrested, prosecuted, and convicted for..

That shows & learn people that justice is just for losers, while winners will be walking in glory.

Which means it's joke, not justice. Justice should be equal for everybody regardless of nationality.

Even more, they will have full (85% american's?!) support of their society to annihilate other civilians?!

That learns to never surrender and you can wipe out entire nations freely?!

That atomic weapons were used ?

Absolutely yes.

Are you suggesting that the Japanese didn't need to be stopped ? Or the Germans ?

To stop unarmed kids and womens you need to annihilate them.. ?

The figure of 175000 casualties from the atomic bombs pales in comparison to the number of Russians killed in WW2.

Russian's didn't die in one second, but during dozen of sieges of their cities.

They had chance to escape (please beware I am talking about civilians victims), but refused to do so, or was forced by russian's dictatorship government to not escape..

So that's partially russian's government guilty for so many civilian's casualties.

If this is a "war is a terrible thing" thread, then I'm in agreement.

 

If this is a "US is a terrible country" thread, then I've lost a little respect for you Sensei.

1) you should watch movie, I am referring to, before replaying..

2) no country should use nuclear weapon to kill people who was no guilty.. on people, who is not responsible to starting war in the first place..

If dictator bombs your country, kill him, not the all hundred millions of people of his nation!

3) there is no excuse for whoever attacked first, when they are starting attacking and bombarding of civilians that are innocent and not guilty!

P.S.

Don't learn your history from Hollywood or Oliver Stone.

I don't learn history from Hollywood or Oliver Stone..

Are you suggesting that this movie is lie?

No single dead of Japanese child is worth dead of american soldier..

Solider is adult going to war for money, while little child is just entering this world, learn how Universe is working..

Yes; millions of lives vs. hundreds of thousands of lives is a rather simple balance.

Will you murder billions of innocent people (or simply living animals?) to survive one of "your's"?

The Japanese attacked the US, so the US went to war with them.

This is very simplified version.

If you would buy assets from other country,

and this country would stole your assets,

what you would do?

US before II world war, stole Japanese assets in US.

So called for population "freezing of assets".

(Recently we have couple examples of this behavior, lucky for you without counter-stike like freeze of Libyan's assets )

US government did everything what they can do start the war..

How to do it? Freeze assets of foreign country...

Hello!

I was just watching "The Untold History of the United States"

http://www.imdb.com/title/tt1494191/

by Oliver Stone,

and crying for couple of the first episodes,

when the people who thought to rule the world,

such as truman,

bombed and murdered and annihilated hundred thousands of people..

truman, his soul is burning in the hell right now for eternity, claimed that he is "happy to hear of successful nuclear weapon tests"... ?!?

85% of americans according to movie, supported mass murdering of hundred thousands of people?!

Are your fathers, mothers, grandpas, grandmas one of these 85% of mass murderers that wanted to annihilate all these hundred thousands children and womens.. ???

Ask them whether they supported using of nuclear weapon to annihilate other people to wipe out kids and womens from this world..

However there are systems in which momentum is conserved and kinetic energy is not. KE is but one form of energy, while momentum is momentum, and is only changed by an external force. Momentum is conserved, for example, in an inelastic collision, but KE is not.

But in such case kinetic energy is converted to heat, or photons. So total energy remain the same before collision and after collision.

Take for example vacuum tube, with two electrodes, and piece of metal between them.

Plug high voltage to electrodes. Electrons are emitted, and accelerated.

They have significant kinetic energy, and upon collision with metal on their path, x-ray photons are created. And their energy will depends on applied voltage.

There was such nice experiment: scientists were accelerating metal balls (dozen/hundreds), and shooting to water, and measuring increase of temperature of water.

Setting the clock, now from Java? It doesn't look very complicated.

http://www.java-tips.org/other-api-tips/jni/set-the-computer-clock.html

Above code uses

Win32 API SetLocalTime() function:

https://msdn.microsoft.com/en-us/library/windows/desktop/ms724936(v=vs.85).aspx

Quote from MSDN (Microsoft Developers Network):

"Remarks

The calling process must have the SE_SYSTEMTIME_NAME privilege. This privilege is disabled by default. The SetLocalTime function enables the SE_SYSTEMTIME_NAME privilege before changing the local time and disables the privilege before returning. For more information, see Running with Special Privileges."

Not to mention you are mixing "Java run in web-browser", with "Java real application"..

"This command can only be executed as an administrator. So we have to start an 'Administrator: Command Prompt' and execute the program from it.To 'Start a Command Prompt as an Administrator' on windows 7 use Start -> type 'cmd' -> hit 'Ctrl+Shift+Enter'. Please refer to Microsoft Technet for detailed steps on how to start an 'Administrator: Command Prompt'"

And once again, people who know less believe to be competent.

You have been asked to write by yourself code,

challenged to prove your own words,

code that you were talking about in post #10:

quoting you "Any malignant website can set your computer's clock to any value"..

And you failed to do so..

But that's no surprise if you really don't see difference between C/C++ compiled code and HTML/JavaScript/Java/CSS etc. opened exclusively by web-browser..

Atomic Clock Sync sets the compouter's clock, it runs completely normally on a sound Windows

http://download.cnet.com/Atomic-Clock-Sync/3000-18512_4-14844.html

and there are many applications like that one. Why do I need to cite one despite they're so well known?

 

Sorry guys, you are wrong. Even if you were one thousand. You'd better check your claims before making strong and wrong statements.

I am speechless shocked by amount of your's incompetence..

So you really (really?!) don't see difference between application that is executable file, compiled to specific operating system, compiled to specific cpu.. that user installs intentionally on his/her own machine..

and remote website, hosted on server machine, that is prepared by hackers, and waiting for victims, to infect their computers (if they manage to).. ?!?

If hacker will prepare virus that pretends real program (Trojan horse: http://en.wikipedia.org/wiki/Trojan_horse_(computing)), and user will install it by himself/herself, that program obviously can get full access to entire computer, and setting it's clock is one of the most ridiculous things hackers can do with that machine I heard about..

If they already have full control over attacked machine (because user did everything for hackers by installing software), there is no reason to play with system clock..

Malicious websites or software setting the clock is perfectly known, and this is why any book trying to be serious about cryptography explicitly tells that

So your "knowledge" about subject is entirely from books that you read,

not your's own experience.

And you dare to write to us per "incompetent"..

To me, and I trust the all other forum members that read it:

"Any malignant website can set your computer's clock to any value".

means that user-victim, will go to remote website, using web-browser, and just visit it,

without having to install anything from that website..

H₂O, D₂O, or HDO are all usable. Depending on what you want them to use.

To drink I recommend H₂O.

To nuclear reactor cooling down I recommend D₂O.

For whatever you want to use H₂O or D₂O, it's cheaper to use Earth's water than travel to Ceres and bring it to Earth..

At least at the moment.

At least until money rules world.. Instead of knowledge..

I up vote +1 post #15... which incompetent person downgrade it.. ???

Salting with the computer's clock is exactly what shall NOT be done.

 

Any malignant website can set your computer's clock to any value - for instance, always the same value,

Enthalpy, please show source code of website JavaScript/Java/HTML etc. that will let you change computer system time.. Or better host it, and we will be visiting it, and telling what time your script set.. Ok?

Whenever they talk about it on the net, saying also "you need to have administrator privileges". f.e.

http://stackoverflow.com/questions/6203857/how-can-i-set-the-system-time-in-java

This

http://www.w3schools.com/jsref/jsref_obj_date.asp

is setting Date object time, not entire system time, AFAIK.

If code managed to get to level it can execute system commands on attacked machine, hacker can simply download/change source of website and look at how security system has been designed..

Einstein FIRST came up with general relativity, which correct me if I'm wrong, only has to do with speed, NOT acceleration. It wasn't until special relativity that he addressed changing speeds. Right?

Special Relativity (1905) was before General Relativity (1915).

Get personal firewall such as Sygate Personal Firewall, or other tool allowing to see packets send by your machine,

write code connecting to MySQL server and sending data, or use MySQL admin,

and see packets and count their sizes..

ps. Sending this reply was 1514 bytes in packet log viewer.

Actually thinking about if that type of universe did exist I doubt any level of thinking could define its laws

Then it's not physics..

Physics is observation of phenomena, measure, record on graph at time t, and make prediction how it will behave in the future (function describing measured object).

One can measure temperature of boiling water, tell the others,

and the next time repeat experiment receiving the same result.

The issue is its completey theoretical. The whole concept behind it basically states that it doesn't follow normal laws of physics I.e. Your definition of volume.

"mine definition of volume" is the same across entire human kind:

http://en.wikipedia.org/wiki/Volume

#1 volume is distance * distance * distance,

if distance is measured in meters, volume is in meters ^ 3.

So, you don't even understand definition of volume.. Right?

#2 matter can be created and destroyed (=converted to photons or other lighter pair of particles).

See pair production http://en.wikipedia.org/wiki/Pair_production

See annihilation http://en.wikipedia.org/wiki/Annihilation

I want to elaborate but I can go on about this for hours,

Have you thought about Hollywood script-writer job? It's for you. They can make stuff up every day..

I would like some feedback to further understand this.

You should start from learning the real physics.

f.e. read article by article from Physics History Database

Too much effort? There is just 200+ entries... But you asked by yourself..

and a horizontally movment of matter means no physically work,

Where did you get such silly idea?

When car is moving it's not doing work?

When you're going, it's horizontal movement (unless you jump, or use stairs).

Are not you tired after walking 10 km, 20 km, 50 km.. ?

If you're tired, you spend energy, burned fat and/or sugar.

ps. More precisely when v=const, it's not doing work. When v=0 m/s, then v=1m/s, then again v=0m/s, then there was work. Energy spend on acceleration.

sorry but this "machine was presented several times,

There is no machine AFAICS,

there is you who is moving metal looking thing back and forth, on these videos.

Machine would work by itself, after pressing button..

Video was published in May 2013. 2 years is plentiful of time for building real device, real machine, if it would work..

I meant fleet tracking http://www.tracker.co.uk/fleet-tracking/

It can do things like tell your employer when you deviate from your course and where you went to during that time.

Such device/service has sense: truck hijacking were very common here in '90 years. So any change of path from normal (=optimal,shortest) should be immediately sent to truck company supervisor. After all it could be hijacking..

Power Wall has been introduced with a price tag of $3500 for 10 kWh system,

This price seems ridiculous, to me at least.

The first accumulator from net 12 V 120 Ah = 1.44 kWh, 2 years warranty, 86 usd.

To have 10 kWh there is needed 7 pieces, 86 usd * 7 = ~603 usd.

6 times less..

Better than tracking trucks with GPS forcing truck drivers to do ridiculous working hours and stick to certain routes with threats of being fired if they don't.

???

Limiting time spend by truck driver @ road, and forcing him to go sleep/rest periodically you call "ridiculous working hours".. ?

Without limits and tachograph they used to be working 24+ hours because their employer had "emergency delivery" (as always)..

Truck drivers that don't rest regularly are serious risk for other road users, and causing serious disasters on roads. They are falling asleep while driving and crashing..

ps. That's police who is checking their tachograph in the first place, not employer.

Employer want to know where is their truck and cargo (worth hundred thousands or millions, so they have right to know, using GPS, even plugged to each container).

A lot of folks come here to express skepticism about a particular concept, hypothesis, or theory,

The truth is these people have their own (pet) theory that provided by us data is overthrowing..

If these people just came with question, received answer, they're grateful for knowledge.

They thank for learning something new.

But not layman-with-theory.

This is one with which I have a quibble. Human power is far from green. You have to eat food to replace the calories you burned, and are responsible for all of the impact of that food in such an analysis. Just because you push it out of sight doesn't mean it's not there.

But production of food consumes current (+-1 year) Sun energy, takes CO2 from atmosphere and converts it in plant cells, eat by animals, and this way at 1st or 2nd stage, goes to human body.

While burning fossil fuel releases CO2 absorbed millions years ago.

People have to eat regardless whether they work or not.

Whether they work on something important, or something meaningless.

Optimally they should do something useful for population.

There is a broad reason we have historically employed machines to do work for us, and it's not laziness.

Money. Greedy.

Machines don't strike.

Machines don't want rise..

That's the main reason..

Actually it should be possible to measure/check in laboratory experiment.

Imagine beam of electrons emitted by electron-gun inside of vacuum tube.

Couple such setups f.e. 3 with slightly offset between them.

On one side there is electromagnet.

Electron guns are emitting electrons:

1) when electromagnet is turned off

2) when electromagnet is turned on

We know distances between electron beams and each electromagnet. And can deduce whether change in direction of electron beam is delayed or not.
