Both visible light and radio waves are types of electromagnetic wave.Although radio and visible light are both electromagnetic waves, there is one thing that is very different—the way that they interact with matter.
To theorists puzzling over the physical meaning of renormalization, QED hinted that the electron had two charges: a theoretical charge, which was infinite, and the measured charge, which was not.
Keef Knight, the protagonist of Hulu’s surreal new social justice comedy Woke, talks to his markers.Prior to the police brutality, Knight—played by Lamorne Morris, finally getting his own sitcom after many years of carrying New Girl on his back—was broke, complacent, and liked to “keep it light.” His roommates are a goofy, ultimately loveable but also unsettling send-up of San Francisco: Clovis (T.
That was 130 years ago—now the observatory is plopped right above one of the most densely populated areas of the US!” How could Lick compete with the likes of the Hubble Space Telescope , which orbits far above both light pollution and smog?
“We were extremely saddened by the news out of Arecibo,” says Andrew Siemion, the director of the Berkeley SETI Research Center.Earlier this year, the [email protected] project stopped pulling in new data from Arecibo and other radio telescopes so its researchers could focus on analyzing the data already collected.
“I see it as kind of a Wright brothers moment on another planet,” says Bob Balaram, the chief engineer for the Mars helicopter project at NASA’s Jet Propulsion Laboratory.
The BioSCAN project started when Brown bet a museum trustee that he could find a new species of insect in her backyard in West LA.In its first three years, Brown and the backyard collector discovered 30 new species of insects and published their results.
Unlike CHIME, which looks at small chunks of the sky at any given time, Caltech’s Survey for Transient Astronomical Radio Emission 2 (STARE2) telescope observes the entire sky at once, which allowed the Caltech team to quickly confirm that the burst was extremely powerful.
They say it allows anyone with a laptop and less than a thousand dollars of equipment—just a telescope and a $400 electro-optical sensor—to listen in on any sounds in a room that's hundreds of feet away in real-time, simply by observing the minuscule vibrations those sounds create on the glass surface of a light bulb inside.
Plagues don't come explicitly for one tribe or another; they don't smite a population because it's gone astray; they're neither divine punishment nor a sign of the Rapture.
Turyshev’s plan would take advantage of this effect by sending a telescope on a 60 billion-mile journey to the sun’s focal region to photograph a habitable, Earth-like exoplanet that is up to 100 light years away.
Dangerzone also uses the optical character recognition software Tesseract to convert letters and numbers in the PDF back to machine-readable text, letting you copy text from and search the file.
Haupt, who works as an astronomy instrumentation engineer at Brookhaven National Laboratory in New York, detailed how she took the rotary mechanism from an old Trimline telephone, paired it with a microcontroller and an Adafruit Fona 3G cell transceiver, put it all into a 3D-printed casing, and built something that could replace her daily flip phone.
And yet: Lots of folk still think advancements like ride-hail and autonomous vehicles might be a balm to terrible traffic, and that tech innovation plus regulation could lead to fewer emissions and less time sitting behind the wheel.

The real legal questions are two: Did he violate the Griners’ right of publicity, and can King prove that his campaign’s version of the meme is a fair use of Griner’s copyrighted material?
In the last sixteen years Spitzer has revealed the universe to us, including helping scientists understand how galaxies form by revealing cold and impossible to see clumps of gas.Photograph: NASA/JPL-CaltechThis image of M82, also known as the cigar galaxy, is 12 million light years away.
The star on the right shoulder of the Orion constellation is a red supergiant called Betelgeuse.Photograph: ESOThis image, taken by the European Southern Observatory's Very Large Telescope, shows how huge and lopsided Betelgeuse really is.
It's counter-intuitive, but it turns out that letting slower passengers board first actually results in a more efficient process and less time before takeoff, according to a new paper in Physical Review E.
At the beginning of this year, the science fiction and fantasy magazine Clarkesworld published a short story called “I Sexually Identify as an Attack Helicopter” by Isabel Fall.
As Liverpool soccer player Roberto Firmino clutched out the only goal of the club's December 21 FIFA Club World Cup match before a live audience of over 45,000, at least twice as many fans were tuned in somewhere better suited to FIFA 20, the video game: the streaming platform Twitch.
They hope that this new kind of organism—contracting cells and passive cells stuck together—and its eerily advanced behavior can help scientists unlock the mysteries of cellular communication.
Photograph: NASA/JPL-Caltech/Penn State/DSSThis infrared view from NASA’s Spitzer telescope reveals even more texture and activity in this busy region.Photograph: NASA/JPL-Caltech/University of WisconsinIn this image from the Hubble Space Telescope, the center of the Swan Nebula appears shrouded in a cloud of hydrogen gas.
This dish antenna rises seven stories above an ancient seabed in the Karoo, a remote semidesert in South Africa.Combined, they'll form a single observatory called the Square Kilometre Array, the largest scientific structure on the planet, to gather 10.8 million square feet of radio waves.
The photo was taken with NASA’s Wide-field Infrared Survey Explorer—a telescope with a very wide lens that looks at the universe in infrared light.
A group of microscopic algae that form vast aquamarine blooms off the east coast is the subject of NIWA’s latest Biodiversity Memoir.Measuring as small as three microns (0.003 mm), powerful scanning electron microscopes are needed to look at the algae in detail.
Based on the altitude and flight characteristics demonstrated in a short video, Kitty Hawk appears to be relatively far along with the aircraft, compared with other electric vertical-lift aircraft (aka flying car ) efforts, many of which have showed concepts and prototypes but haven’t flown much.
