Relativity

The crowning achievement of the 18th-century researcher was the design of the first experiment to measure the force of gravity between masses in a lab

I’ve always been an Edgar Allan Poe fan, so much so that I even watched the horrifying—not in a good way–2012 film The Raven.

The Christmas holiday approacheth, and for those of a Maker bent, here’s how to Build A Sled For Slinging Snowballs — Winter Warfare Will Never Be the Same.  If you’re more the craft-y sort, now you can deck the halls with Nobel physicists with this physics twist on the craft of cutting paper snowflakes.

In astronomy, bigger is almost always better. The size of a telescope’s aperture (or primary optical element) not only determines how many pesky little photons it can capture, but also the ultimate resolution of the image that can be formed.

Not long ago I came across a piece in the Scientific American archives from the earliest days of very-long baseline radio interferometry, the technique employed by the Event Horizon Telescope.

Should you happen to live in the United Kingdom, Matt Parker — a.k.a. @StandUpMaths on Twitter — probably needs no introduction.

I love apostates, believers in or, better yet, conceivers of a theory who turn against it. They restore my faith in science, because they show that scientists can overcome attachment to their own brainchildren, a feat that is essential for progress and cannot be taken for granted.

In the last few years, stories have abounded in the press of the successes of the Large Hadron Collider, most notably the discovery of the Higgs boson.

Here’s a disquieting thought for your weekend: Dark Energy Might Be Stealing the Glue Holding the Universe Together. A new invisibility cloak simultaneously works for heat flow and electrical current.

I’m writing this post for two reasons. One is to recommend a new book by Columbia astrobiologist Caleb Scharf (who also writes a terrific Scientific American blog, “Life, Unbounded“), and the other is to defend an old book of mine.

Christopher Nolan’s new film, Interstellar, is a near-future tale of astronauts departing a dying Earth to travel to Saturn, then through a wormhole to another galaxy, all in search of somewhere else humanity could call home.

This winter an airborne experiment named Spider will probe the earliest remnants of the universe
