What’s the Universe Made Of? Math, Says Scientist

MIT cosmologist Max Tegmark believes the universe is a mathematical structure. BROOKLYN, N.Y. — Scientists have long used mathematics to describe the physical properties of the universe. But what if the universe itself is math? That’s what cosmologist Max Tegmark believes. In Tegmark’s view, everything in the universe — humans included — is part of a mathematical structure. All matter is made up of particles, which have properties such as charge and spin, but these properties are purely mathematical, he says. And space itself has properties such as dimensions, but is still ultimately a mathematical structure. “If you accept the … Continue reading What’s the Universe Made Of? Math, Says Scientist

What is the Fibonacci Sequence?

The shapes of spiral galaxies, such as Messier 74, and hurricanes, such as Hurricane Irene, follow the Fibonacci sequence. The Fibonacci sequence is a series of numbers where a number is found by adding up the two numbers before it. Starting with 0 and 1, the sequence goes 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, and so forth. Written as a rule, the expression is xn = xn-1 + xn-2. Named after Fibonacci, also known as Leonardo of Pisa or Leonardo Pisano, Fibonacci numbers were first introduced in his Liber abaci in 1202. The son of a … Continue reading What is the Fibonacci Sequence?

SpaceX is about to launch two of its space internet satellites — the first of nearly 12,000

Now that the dust has settled from SpaceX’s first Falcon Heavy mission, the company is getting back to its routine with another Falcon 9 launch. The rocket is slated to take off from California this morning, sending up an Earth-observation … Continue reading SpaceX is about to launch two of its space internet satellites — the first of nearly 12,000

Why Do Rockets Explode?

This screen grab from a video by USLaunchReport.com shows the explosion of a SpaceX Falcon 9 rocket on Sept. 1, 2016. The world might be watching rather apprehensively as Elon Musk’s SpaceX readies the launch of its Falcon Heavy, the most powerful rocket since the legendary Saturn V — the heavyweight launcher that propelled humans to the moon. Many still remember the September 2016 launchpad explosion that wiped out not only SpaceX’s workhorse rocket Falcon 9 but also an Israeli telecommunications satellite. This wasn’t the first disaster in SpaceX’s history. A little over a year before that, in June 2015, … Continue reading Why Do Rockets Explode?
