Dr Karl's science hour on triple j is the station’s longest running segment, loved as much today as it ever has been. Every Thursday, Dr Linda and Dr Karl solve the mysteries of the world, with science. Only triple j listeners could come up with questions as hairy as these.

If you study a map of the Cosmic Microwave Background, or CMB, you may notice a large, deep blue splotch on the lower right. This area, creatively named the Cold Spot. Is this feature a statistical fluke, the signature of vast supervoids, or even the imprint of another universe?

A spiral galaxy is a class of galaxy originally described by Edwin Hubble in his 1936 work The Realm of the Nebulae and, as such, forms part of the Hubble sequence. Most spiral galaxies consist of a flat, rotating disk containing stars, gas and dust, and a central concentration of stars known as the bulge. These are often surrounded by a much fainter halo of stars, many of which reside in globular clusters. About 77% of the observed galaxies in the universe are spiral galaxies. Our own galaxy, the Milky Way, is a typical spiral galaxy.

Generating plasma inside a microwave

Plasma is one of the four fundamental states of matter (others are solid, liquid, and gas) and the most abundant form of matter in the Universe. It is comprised of ionized atoms with either a positive or negative charge and free electrons. 

As the match burns, electrons are torn from their atoms when chemical bonds break within molecules. Normally those electrons would immediately be re-captured to form the byproducts of combustion. However, the energy provided by the microwave radiation causes this cloud of intermediate ions and free electrons to persist in a semi-stable state. The intense light is a result of these high-energy particles losing energy before being re-energized by the microwave. When the microwave is turned off, the plasma will immediately dissipate since it no longer has the requisite energy to exist. 

WARNING: Doing this could damage your microwave! Also, if you're going to record a video of your microwave, please clean it beforehand.

I sometimes wonder if , on the whoe, humans have a preference for over complexity.

I sometimes wonder if , on the whoe, humans have a preference for over complexity. If you look at the geocentricism side of this animation, it looks like a crazy ballet dance, a mad spirograph of the skies. How much mre simple and elegant the model to the left.

Heliocentrism vs Geocentrism

The geocentric model is an outdated description of the solar system where the Earth is at the center of all the celestial bodies. The stars were thought to be fixed points on a celestial sphere that rotated around the Earth once a day while the planets followed complex orbits. This concept served as the predominant cosmological system in many civilizations for centuries until being replaced by the heliocentric model in the late 16th century. In contrast to geocentrism, heliocentrism claimed the Earth and other planets rotated around the Sun.

While the heliocentric model was proposed as early as 300 BC, it was not until the 16th century when a geometric mathematical model presented by Nicolaus Copernicus ushered in the Copernican Revolution. Over the course of the next century, observations by Johannes Kepler and Galileo Galilei helped solidify the heliocentric model as scientific fact. Further observations revealed that the Sun, although the center of the Solar System, was not the center of the galaxy or the Universe.

More bullying shown here - at least robot's able to get up and get away afterwards.

No wonder they build Skynet.

Robot Self-Righting Mechanism

Boston Dynamics, a subsidiary of Google's parent company Alphabet, unveiled the latest design of their Atlas robot earlier this week. Atlas is a bipedal model designed for use both indoors and outdoors and specializes in mobile manipulation The robot is electrically powered, hydraulically actuated, and uses LIDAR and stereo sensors in its head to avoid obstacles and navigate terrain.

The self-righting mechanism demonstrated here is important for returning the robot to its upright and standing position. Bipedal models are easier to knock over than quadruped designs. Boston Dynamics has a dedicated robot abuser who will be a major catalyst for the inevitable robot uprising following the creation of Skynet.

This is described as "An interactive viewer for rooted phylogenetic trees and networks" and it's free (just as well).

This is described as "An interactive viewer for rooted phylogenetic trees and networks" and it's free (just as well). Actually it look pretty interesting even though I don't have a use for it. Apparently the image is "Same tree - seven different views: Rectangular Phylogram, Rectangular Cladogram, Slanted Cladogram, Circular Phylogram, Circular Cladogram, Radial Phylogram and Radial Cladogram:"

Well I'm glad that's cleared up!
