How to Calculate the String Angle of a Kite vs. a Balloon

How to Calculate the String Angle of a Kite vs. a Balloon

And here is the fun part—Munroe states that both a kite AND a balloon could extend over a river.So, at some value of wind speed the kite and the balloon would have a string at the same angle.

New AI-Based Navigation Helps Loon’s Balloons Hover in Place

New AI-Based Navigation Helps Loon’s Balloons Hover in Place

Because winds blow in various directions at each altitude, the AI-based controller was programmed to use reinforcement learning, or RL, to search a database of historic records and current weather reports to predict the best elevation to keep the balloon in one place.

What If the Big Bang Was Actually a Big Bounce?

What If the Big Bang Was Actually a Big Bounce?

In a brief moment of rapid expansion, that burst of energy inflated the cosmos like a balloon.They analyzed how a collapsing universe would change its own structure, and they ultimately discovered that contraction can beat inflation at its own game.

Finally, a Robot That Moves Kind of Like a Tongue

Two stickers with fibers running lengthwise constrain the balloon to make it turn as it inflates (such an actuator could also use hydraulics instead of air, by the way), while a third sticker with fibers running at a 45 degree angle make the balloon twist at the end.

How Loon's Balloons Find Their Way to Deliver the Internet

How Loon's Balloons Find Their Way to Deliver the Internet

Since Loon spun out of X last summer, the company’s balloons have logged 1 million hours of flight time and found some novel ways to navigate the stratosphere.

He is also working on two NASA proposals to send the large balloon reflector to the stratosphere and the Terahertz Space Telescope to orbit.

But the Red Balloon researchers found that the way the FPGA was implemented for Cisco’s Trust Anchor, they didn’t need to map the whole bitstream.

The Government Shutdown Killed an Artist's Space Sculpture

The Government Shutdown Killed an Artist's Space Sculpture

According to the release put out by the Nevada Museum of Art, after the satellite was deployed it successfully established communication with ground stations on Earth, but the sheer number of satellites being deployed meant the Air Force was “unable to distinguish between [the satellites] and could not assign tracking numbers to many of them.” Without a NORAD tracking ID, the FCC wouldn’t give the okay to Paglen’s team to deploy the reflective balloon contained in the satellite.

Scientists Need to Talk More About Failure

Scientists Need to Talk More About Failure

Despite this, scientific failure is rarely talked about openly, which was why when University of Arizona astrophysicist Erika Hamden used her TED 2019 talk last week to share how her work has been characterized by setback after setback, it felt like a radical act.
