How fast can you go? CentralJapan Railway Co.has unveiled a prototype for a new Maglev train that will run betweenTokyo and Nagoya. The train will carry passengers at speeds of up to 500km/h — the fastest land-based commercial speed.

HOW DOES IT WORK?

+

Maglev trains operate via magnetic levitation (hence the name). Powerful electromagnets are used to propel the train along its track.

+

Attraction Repulsion

Unlike conventional trains, it is not in contact with the rails, which minimizes friction and achieves higher speeds.

AND THE ENGINE?

Since the train is propelled due to the interaction between the train and the track, there is no need for an engine.

Elegant Earth Now that we’ve dodged another apocalypse, we take a look at some facts you may not know about the planet we call home.

The Earth is approximately 150 million km from the sun. At this distance,

ALASKA EXPERIENCES A MAGNITUDE 7 EARTHQUAKE ALMOST EVERY YEAR,

IT TAKES ABOUT 8 MINUTES AND 19 SECONDS FOR SUNLIGHT TO REACH OUR PLANET.

and a magnitude 8 or greater quake on average every 14 years.

THE EARTH IS GETTING MORE MASSIVE.

THE NAME “EARTH” COMES FROM OLD ENGLISH

You may feel like you're standing still, but you're actually moving —

and Old High Germanic words (eorthe and erda, respectively) for “ground” or “soil.”

It is the only name for a planet of the solar system that does not come from Greco-Roman mythology.

WHERE YOU ARE ON THE GLOBE, YOU COULD BE SPINNING THROUGH SPACE AT JUST OVER 1,000 M.P.H.

As we plow through space, we accumulate on average 20-40 tons of organic debris per day. Most of it is in the form of teeny dust particles which burn up in our atmosphere. These eventually fall to the ground and pile up or wash into streams and oceans.

AT THE EQUATOR, THE CIRCUMFERENCE OF THE GLOBE IS 40,075 KM.

if you measure it from its base to the apex. Mt. Everest stretches 8,850 m above sea level, but it has a head start due to the general uplift from the Himalayas. The Hawaiian volcano Mauna Kea (right) is 10,314 m, so even though it only reaches to 4,205 m above sea level, it’s bigger than Everest.

As of the 2007 census, 1,660, 714 people lived in 38.55 km². The Antarctic Ice Sheet holds nearly 90% of the world’s ice and 70% of its fresh water. IF THE ENTIRE ICE SHEET WERE TO

What happens in

Zero Zero gravity? Facial ‘puffiness’

• Gravity forces bodily fluids into the lower half of the body. • When released from the pull of gravity, fluids return to the upper half of the body. This is the cause of the round-faced ‘puffiness’ seen in astronauts. • Redistributing fluids around the body itself causes balance disorders, distorted vision and a loss of taste and smell.

Cardiovascular system

Canadian astronaut Chris Hadfield is beginning a five-month expedition aboard the International Space Station. That’s a full five months of your body freely floating around in space. While going weightless may look easy, it takes Space adaptation a heavy toll on syndrome (SAS) Similar to motion sickness your body.

Symptoms include: • Nausea • Vomiting • Vertigo • Headaches • Lethargy

• Reduces work capacity. • Blood rushes to head. • Reduces blood circulation volumes. • Induces dehydration. On Earth

In orbit

+2"

Spinal stress

• Vertebrae stretch, sometimes painfully. • Can cause the human body to be about 2 ½ inches taller in orbit.

Blood flow

• On Earth, hearts are constantly fighting gravity to pump blood upwards. • In zero-gravity, blood rushes unhindered to the top of the body, creating puffy faces and eyes that sometimes bulge.

Muscle atrophy

• Decrease in mass of the muscle. • Leads to muscle weakness. • Muscles will lose 30-40% of their strength. • Strength won't come back for several weeks.

Immune system

• Weakens in zero-G. • Some drugs lose potency in a weightless environment. • Astronauts have been known to experience recurrences of childhood bouts of chickenpox in orbit.
