Near lightspeed space travel - not so cool as we think

have you ever watch a sci-fi movie, in far future when space ship already develop an empire flet move from point a to b with FTL jump(faster than light) and enter hyperspace?? the stas outside turn into long streaks of ligh and you're off.

its onne of the most memorable scene in space travel ever created, but its also likely turn out to be pretty far from reality. according to a study by a group of students from the U.K.'s University of Leicester.

The study, titled "Relativistic Optics Strikes Back," was published in the University of Leicester's Journal of Physics Special Topics. You can indulge in all the delicious physics equations in the abstract.

lets imagine if there a certain space ship accidentally wandered in our solar system, on direct course to our sun, and if the space ship engaged in near lighspeed travel, the light,star,universe around it wouldnt appear to stretch out, but it would look more like dis of like (like in wallaper)

The Doppler effect is to blame for spoiling George Lucas' vision of high-speed space travel. In this case, it's a Doppler blue shift caused by electromagnetic radiation (including visible light) moving toward the observer. According to a release on the study, "They would simply see a central disc of bright light as Cosmic Microwave Background Radiation is shifted into the visible spectrum."

the study didnt just ruin our imagination but it also show that pressure would pretty much unbearable. The pressure on the spaceship would be like having it at the bottom of the ocean. On top of all that, harmful X-ray radiation would be a major problem for Wookiees and humans alike.

with this we know why we need "fiction" in "science fiction" if a certain space ship If the Millennium Falcon clung stubbornly to the laws of physics, the whole space battle animation franchise wouldn't be nearly as much fun.

The biggest thing in the universe

human, yes that us organic being who habitated a planet called 'earth' now there 7 billion human live, with unimagnable evolution progres from ancient age to modern age from time when we must walk 3 month to today when we just need 30 minutes.

we always though how great human was, an incredible organ 'brain' the most clever being in earth, that is what we thought last month but i doubt we still can think like that.YOU and I are small, really really really really small more small than dust in universe at least when compared with the size of the largest 'known' item in universe.

that is picture our solar system and that is how big our planet that have 7 billion people compared with size sun, and wallpaper i use is picture of galaxy. There hundred or thousand that scientist 'found' in our universe, but recenty an big shock hit us human that might be able change or view to universe.

Last week, a team of astronomers based in the U.K. discovered the largest object in all of our observable existence: a celestial structure made up of 73 quasars that is up to 4 billion light years long.

How big is that exactly? Well, it would take tens of thousands of our own Milky Ways -- the big, galactic one, not the one that comes in a wrapper -- to equal the size of Huge-LQG (for Large Quasar Group), as it's become affectionately known.

wow, big isnt fit word to discribe that size, huge also not good enough, just like how ant compared to biggest dinosaurus i think, 10.000 more big than our galaxy.

Feel insignificant yet?

Yes, it does seem like something so inconceivably massive should have been noticed by now, and that's actually the most interesting part of the discovery.

The discovery of an astronomical body so large throws doubt upon one of the basic assumptions of the nature of the universe. That notion, known as the cosmological principle, assumes that the little corner of the universe we're able to observe from this particular rock is a reasonable sample of what the rest of the universe must also be like.

But Huge-LQG turns out to be so huge that it makes up a few percentage points of the observable universe on its own. It's a little bit like if we suddenly discovered a 51st state that consists entirely of a single building the size of Iowa.

maybe found other living being like alien, and other sci-fi stuff wont be strange again in this vast universe.So not only are we less than the most insignificant of specks in our universe, we apparently don't know nearly as much about that universe as we thought.

Famibot your home guardian and cleans your air

LAS VEGAS - still in CES 2013, if last time there a iRobot Mirra 530 pool cleaning robot, now robot to cleaning air and your house called famibot and minibot.

People are getting used to having robot running around their house like animal robot and baby vehicles.

chinese vacuum-maker Ecovacs, though want more functionality in domestic bots, at CES 2013, they demonstrated its famibot and minibot.

its primary function is to roam around your floor and purify the air, when it senses a particulary dirty zone, it will focus on that area. equipped with camera, famibot can act as a telepresence robot when you not in home, giving video what going on at home, make chat with people.

it can also play music, remote control of connected household appliance like air conditioner or light.

Ecovacs staff put it through its paces, though interference from las vegas convention center venue messed up wireless command and it was slow to respond.

other feature is famibot can also send alert if it detect unexpected person in the home, or smoke from fire.

minibot is famibot companion, its have all famibot feature except air purifying.

Ecovacs says those two should hit US market in firts half 2013, with famibot at $899, and minibot at $449

iRobot Mirra 530 Pool Cleaning Robot

LAS VEGAS - still in CES 2013 there another interesting stuff.

iRobot Mirra 530, mirra its robot pool bots. you must have try to cleaning your pool with long, unweldy nets and hoses, and always gave up in frustration.

Mirra 530 would have been a huge help, now being show off at CES 2013, it improves upon the company's Verro pool bots.

with its rotating brushes, Mirra is desain to scrub any type of in-ground pool without using the pool's filtration system, a concept aimed at saving energy.

Unlike the $1,099.99 Verro 500 PowerScrub, the $1,299.99 Mirra has wheels instead of treads and a more powerful suction and filtration system.

Mirra can pump and filter about 70 gallons of pool water per minute and suck up debris as small as 2 microns.

Its iAdapt Nautiq technology allows it to suss out the dimensions of the pool and choose the most efficient way to rid all surfaces, from the bottom to the waterline, of everything from hair to bacteria.

It can hug walls, handle steps, and automatically dodge obstacles. Also, it won't get its 60-foot floating power cord tangled up.

When you yank it out of the water, you just empty the two filter canisters of debris, then drop it back in next time.

truly effective just put Mirra in your Pool she will start cleaning, mean while you can do other thing.

Mirra will be available this spring in select countries, along with iRobot's Looj 330 gutter-cleaning robot, which is already on the U.S. market.

Atom Shredder - Introduction

Our current knowledge about the atomic pattern partly caused by a device called an particle accelerator or a atom shredder. These machines accelerate or speed up the filling particles "in the form of negatively charged electrons or positively charged protons, deuterons, or alpha particles" at high energy. Electrons are particles of negative electricity that surround the nucleus or atom's seed inside. Protons, deuterons, and alpha particles are positively charged all atomic nucleus. Proton is ordinary hydrogen nuclei; deuteron is heavy hydrogen nuclei; alpha particles are helium nuclei.

Heating System

Water Heating System

The water heater is used to provide hot water for the kitchen, bathroom, and washing is based on the principle of convection. A heater coil mounted on the boiler so that the water in the kettle it through freely. When the coil is heated water in it to be warmed by the heat flow through the metal wall of the coil is by conduction.

Convection

Which we call convection is actually a combination of conduction through a fixed medium and convection, while heat carried by a moving medium. for example if there is running water, say in contact with a hot surface, some liquid was heated by conduction and heat it brought along with the moving liquid. If the water is warm then come into contact with a cold surface, the water will give a portion of its heat to the surface, again through conduction.

Isolator

Many other events that show the insulating properties of air. The house as often isolated by arrangement dual wall, air space formed between the outer wall and the plaster walls. Insulation is made more effective way by placing the material is more loose. As mineral fibers in the air space, preventing air circulation inside the dual walls it.

Conduction

when an object attached to other objects, the temperature will rise in this place. The molecules vibrated faster even though stay in place, the molecules that transmit the vibrations to the surroundings. That's how the heat propagates through conduction.
