Glassified a project from the MIT Media Lab is a ruler with a transparent screen on one end.
Creative Applications Network Great to see more ideas using the 4d systems transparent OLED display module!
Interesting thing would be nice wireless and if need a battery a transparent one. And pray tell why would I want to measure the angles of a hand-drawn triangle as indicated as one possible use for this contraption?
So Slide-rules are superior to calculators abacuses are superior to computers gas lamps to electric lighting and so on?
Something tells me the ruler will eventually be Wifi capable and then you will really see it become useless among teenagers.
Overall I think the abundant existence of pocket calculators on phones and a computer at every turn means we'll be alright without everyone knowing how to do too much math in their head.
We'll leave it to the engineers and specialists as we have many other skills throughout history.@
For why would anyone want to argue between a slide-rule to a pocket calculator or an abacus to a computer.
At least NASA acknowledges that specific conditions have to take place like the angle for viewing the sun's position your altitude
#If The Sun Went Out, How long Could Life On earth Survive? If you put a steamy cup of coffee in the refrigerator it wouldn't immediately turn cold.
Likewise if the sun simply turned off (which is actually physically impossible) the Earth would stay warm at least compared with the space surrounding it for a few million years.
Millions of years after that our planet would reach a stable âÂ#Â00°the temperature at which the heat radiating from the planet's core would equal the heat that the Earth radiates into space explains David Stevenson a professor of planetary science at the California Institute of technology.
Although some microorganisms living in the Earth's crust would survive the majority of life would enjoy only a brief post-sun existence.
Of course the sun doesn't merely heat the Earth; it also keeps the planet in orbit.
If the sun were to disappear as in*poof*-It's gone. It would take 8 minutes for the earth to go dark
and at least 12 of those satellites would come crashing to Earth. In fact every space satellite in our new trajectory would immediately come crashing down to Earth the satellites on the far side of earth would be left behind trailing in Earth's gravity.
Earthquakes would start moments later due to the sudden gravitational shift Some of our atmosphere will be lost
No worries as most that atmosphere protected us from a sun that is no longer shining or at least will stop shining within 7 minutes 30 seconds...
Women and Minorities Hardest Hitif the suddenly the sun went out'poof'as this article suggest that thing which causes this event would surely have an effect at the same time On earth
since we do reside within the atomosphere distance of the Sun and that same thing
of which'great power causes the sun to go poof'surely would destroy the Earth as well. By the way the sun has a hot riotous atmosphere called the corona that reaches from the sun's surface past Earth all the way to Pluto and beyond.
The corona is seen seldom only during a total eclipse but it is there. To be more accurate the Earth wouldn't immediately fly out
if the sun lost its mass instantly; it would continue to orbit its current trajectory for about 8 minutes as not even the effects of gravity move faster than light.
or satellites would suddenly stop being caught in our gravity well...our speed wouldn't change
Immediate death is not in the sun's future since it is a star. Currently scientists have deduced that our sun is 4. 5 billion years old
and is about at its midlife. Like all stars as the hydrogen fuel in the core is used up the outer parts of the Sun will begin to expand.
The Sun will turn from a yellow dwarf then into a red giant. By the time it is 10 billion years old it will have transitioned into a red giant
and its atmosphere will stretch out to near where the Earth is located and will almost engulf it in its orbit.
and the Sun will be at the center of a planetary nebula. The odds of humans creating a black hole On earth is more likely than the sun suddenly poof is off.
Do not fear the sun but fear humanity as our future killer. DCRANE:..as not even the effects of gravity move faster than light.
On the contrary: Gravity operates outside of space time. Its effect is instantaneous -otherwise you would have celestial objects orbiting each other based upon where they'used'to be.
or satellites would suddenly stop being caught in our gravity well. A satellite is orbiting earth
and both are orbiting the Sun . If the Sun disappeared Earth's trajectory would immediately change.
Any object that is in the path of this new trajectory would suddenly fall into Earth's gravity
and burn up or impact it. This includes the moon. Dcrane: Your wrong. If the sun went poof the gravity goes poof
and it's instantaneous as gravity is constrained not by the speed of light. It's either there
A quick Google search makes it clear why you all are having such a hard time reconciling your different interpretations of the question:
For example even though the Sun is 500 light seconds from the Earth newtonian gravity describes a force On earth directed towards the Sun's position now not its position 500 seconds ago.
In the case of a disappearing sun (whatever that even really means; it's hard to discuss physics problems
'but let's consider that'poof'=the sun flies away from the solar system at some absurd speed close to the speed of light) the sun's velocity is not constant anymore so you cannot continue to use the'basically instantaneous'argument.
but during that 8 minutes it would be orbiting as normal in that it wouldn't'lag'behind the sun.*Another way of looking at your discrepancy is to remind you all that relativity does away with an ABSOLUTE frame of reference.
To say the the Earth would fly off the exact moment the sun'poofed'is meaningless for no such objective moment exists.
Earth seeing where the sun is exactly when the sun sees where the sun is.
I apologize for this gigantic comment but it really is a very difficult concept to wrap our heads around.
it's physically impossible for the sun to ever just go'poof'via some hypothetical evil Zeno and his magical death ray.
This does not mean Earth experiences a frame delay and orbits an 8-minute old sun position;
The same goes for all satellites. They would retain their direction and speed (aka angular momentum) in relation to the only center of gravity the still have
Strictly speaking this is valid for'low'earth orbits only such as the GPS satellites'.'Very high orbits (in the range of 100.000 of km) actually will become more'round'as the nonlinear effects of the sun's gravity field fall away.
Basically the system goes from an uncalculatable three-body problem to a rather simple two-body one
Oh yes and gravity*does*work at the speed of light you might check wikipedia on'gravity waves'.'Sorry JRHELGESON the only thing that was correct in your post was-most probably-your name.
-Of course according to science the sun would never just disappear into nothing so his disappearing act would violate most conservation laws
and faster than light is no more fantasious that supposing that the sun itself would disappear with no trace.
But if the sun just stopped existing and that were the only violation to science then:
and that earth actually rotates not around sun but nearly around the sun was 8 minutes in the past.
Gravity doesnã¢Â#Â#t operate outside space time but is distorted space time. 2-The Moon would continue rotating around Earth with little change.
Both the Earth and Moon are on free fall around the sun so the sun doesnã¢Â#Â#t affect much of the internal working of the system.
and a little slower around earth orbit depending on his distance to sun but the effect is small.
Both the Moon and satellites would change his trajectory nearly exactly the same as Earth.
For that reason most satellites would not change his orbit near Earth except the ones linked to Earth-Sun lagrange points.
but no satellite would have a significant change on his orbit and none would crash on earth. 3-No significant earthquakes and no atmosphere lost.
dissappearing sun is not impossible-imagine some unknown dimensional rift or alien tech that simply relocates sun in a blink of a eye.
While nature wont survive-humans will at least a portion of us. We are evolved enough to survive in freezing climate.
A few days later a new and better science website would go up and Earth would be slightly happier.
The article is about the heat from the sun hypothetically disappearing. The last paragraph about the mass of the sun being affected is really the cause of all the confusion.
It's a bit of an unnecessary tangent and might actually make for a good follow-up article.
I would have preferred that the author answered the original question âÂ#Âoeif the sun went outã¢Â#Â
Assuming you stop eating at the point the sun stops shining âÂ#Âwhich would be the case for some of us âÂ#Âhow long would it take to starve
but then that would be gone say a few months after the sun stopped shining at which point the human death rate would quickly accelerate and at
So by the end of the second year after the sun stops shining (more or less) all humans will be dead
if the sun stops shining so the mere âÂ#Âoeexistenceã¢Â# of that technology would not be our salvation other than to be useful to some
and light from the sun in near-instantaneous fashion it's not hard to visualize something highly improbable yet entirely consistent with the laws of physics.
(so that they aren't initially blocking any significant amount of heat/light from the Sun)
and then all rotated to have their major planar surfaces facing towards the center of the Sun. With a proper arrangement
and timing the net effect as seen from the Earth is that the Sun simply turns off in an incredibly short period of time (just long enough for each of the panels to rotate 90 degrees)
the Sun could be made to turn off in a few moments for all practical purposes as far as the Earth is concerned.
not that we could do anything about it anyway) Wouldn't that have some of the effects of the Sun going out?
despite no radiation from the Sun reaching the planet ever again. Tough but doable. The caveats in that previous paragraph are the much larger obstacles to overcome in my opinion.
Vektor so what youã¢Â#Â#re saying is that the sun isã¢Â# irrelevant?
Maybe we should devise a plan to turn off the sun would you suggest that? We need photosynthesis without it we all die.
If the sun stopped shining there would be widespread global panic and confusion it would NOT be business as usual.

This pipeline which would bring oil from Canada's tar sands to the Texas Gulf Coast needs a presidential permit to move forward.

But the pipeline endangers the environment in many ways. It cuts through precious aquifers in the arid West

All you Alarmists always preach the evidence yet you have no proof beyond skewed computer models and half graphs.
@riff raffcheck the data from ice cores for the past 400000 years. Every 10000 years or so our temperature has spiked to 2-6 degrees warmer than it is today
As a software engineer I have to add something. Computer models are a joke if you don't know what their variables are scaled on.
Most models can't be done without assumed properties of some variables. For example to calculate a model of shooting a projectile across a distance on earth has a few knowns and a few assumed variables.
There is so much mysticism involved around software that makes people believe it over common sense. A bunch of lame arguments not backed up by evidence.
Even though I am not a climatologist as an computer scientist I can smell bs from a mile away.
I don't have to make up reasons to have software engineers exist. So I can concentrate on my craft instead of making belligerent predictions to hype up concern in my field.

#The Garbage Manin December 2001 American environmental activist Jim Puckett traveled to the town of Guiyu in southeast China to look for old computers.
Towering piles of monitors printers and fax machines lined streets and occupied front yards. In a neighboring village women cooked circuit boards curbside in woks and children played atop ash heaps.
Puckett met people blackened head-to-toe with printer toner. Villagers explained that Guiyu now specialized in recycling electronics
In a village dedicated to plastics recycling Puckett found young women sitting on a concrete floor bashing computer housing to pieces with hatchets.
Puckett works for Basel Action Network (BAN) a group that monitors the export of hazardous waste.

#Mix of graphene nanoribbons, polymer has potential for cars, soda, beera discovery at Rice university aims to make vehicles that run on compressed natural gas more practical.
By adding modified single-atom-thick graphene nanoribbons (GNRS) to thermoplastic polyurethane (TPU) the Rice lab made it 1000 times harder for gas molecules to escape Tour said.
The researchers acknowledged that a solid two-dimensional sheet of graphene might be the perfect barrier to gas
but the production of graphene in such bulk quantities is not yet practical Tour said. But graphene nanoribbons are already there.
Tour's breakthrough unzipping technique for turning multiwalled carbon nanotubes into GNRS first revealed in Nature in 2009 has been licensed for industrial production.
But the overlapping 200-to 300-nanometer-wide ribbons dispersed so well that they were nearly as effective as large-sheet graphene in containing gas molecules.
The GNRS'geometry makes them far better than graphene sheets for processing into composites Tour said.
Tour is the T. T. and W. F. Chao Chair in Chemistry as well as a professor of mechanical engineering and materials science and of computer science at Rice.
The Air force Research Laboratory through the University Technology Corp. the Office of Naval Research MURI graphene program and the Air force Office of Scientific research MURI program supported the research.
