The Secret of the Fibonacci Sequence in Trees

"I am the Lorax. I speak for the trees. I speak for the trees for they have no tongues."

—Dr. Seuss (The Lorax)

People see winter as a cold and gloomy time in nature. The days are short. Snow blankets the ground. Lakes and ponds freeze, and animals scurry to burrows to wait for spring. The rainbow of red, yellow and orange
autumn leaves has been blown away by the wind turning trees into black skeletons that stretch bony fingers of branches into the sky. It s... (View original article)

Cornell Chronicle: Sounds of fire and impact

Aug. 8, 2011
Computers synthesize sounds -- from fire to frictional contact -- to go with graphics
Provided/Doug JamesRapid movement of heated gases generates high-frequency sounds that are an important part of the sound of fire, but computer-generated images don't simulate those details. Cornell researchers synthesize low-frequency sounds to match the graphics, then map in the highs based on the sounds of real fire.Provided/Doug JamesPound your fist on a table and the noise will include cha...

Earth May Have Had Two Moons : Discovery News

A new hypothesis claims the Earth may once have had two moons, which eventually crashed together forming our current celestial partner.

This new idea, reported in the journal Nature, could explain a long standing puzzle about the differences between the near and far sides of the lunar surface.

The near side is relatively low and flat with many large dark basalt mare, while the far side is high and mountainous, with thicker crust.

The work, based on computer simulati... (View original article)

Looking Back: The Top Ten Physics Newsmakers of the Decade

January 1st brought not only a new year but an entire new decade. Usually in this issue, APS News looks back over the biggest news stories of the last 12 months. However, with the dawning of a new decade we wanted to take time this issue and highlight not just the biggest physics newsmakers of 2009, but the biggest physics newsmakers of the last ten years. These are the stories that may or may not have the most lasting physical significance, and may or may not have had the most impact within... (View original article)

BBC News – Time travel: Light speed results cast fresh doubts

26 July 2011
Last updated at 05:46 ET

Physicists have confirmed the ultimate speed limit for the packets of light called photons - making time travel even less likely than thought.

The speed of light in vacuum is the Universe's ultimate speed limit, but experiments in recent years suggested that single photons might beat it.

If they could, theory allows for the prospect of time travel.

Now, a paper in Physical Review Letters shows that ind... (View original article)

Lost 1967 Spaceship Found Crashed on Dark Side of Moon? –

Scientists may have just found a lost 1967 spacecraft that took “the picture of the century” before crashing on the Moon.

The Lunar Orbiter 2 was sent to the moon to map out possible landing sites for the Apollo missions, and although its efforts weren't the most successful, the spacecraft made its mark in history for taking a photograph of the lunar surface (shown above) widely considered the “picture of the century.”

NASA intentional crashed the ... (View original article)

NASA plans most ambitious mission to the asteroids

U.S. President Barack Obama has said the objective is to eventually send astronauts to asteroids, Mars and other destinations in deep space. File photo

NASA will have to accomplish its most ambitious mission — landing on an asteriod within 15 years, after a presidential directive.

The challenges are manifold, but NASA nerds are delirious at tackling the nitty gritty of such an inconceivably challenging project — though Hollywood has already done i... (View original article)

Technology News: Emerging Tech: Scientists Untangle Tough Quantum Computing Knot

New research may provide the answers to overcoming one of the biggest obstacles standing in the way of the development of quantum computing: quantum decoherence. The experiment used molecular magnets, which suppress extrinsic decoherence. Extrinsic decoherence was reduced to the point where it was no longer observable, said USC's Susumu Takahashi.

A team of scientists has achieved what might prove to be a breakthrough in quantum computing.

The group has managed to partially ... (View original article)
