  1. Re:The Romans didn't do mathematics on 'To Live Your Best Life, Do Mathematics' (quantamagazine.org) · · Score: 1

    You don't need zero to prove the square root of 2 is irrational. You only need to prove that it is not equal to a fraction, i.e. an integer divided by another integer. All they needed were positive integers.

    Yet, it was man rated. So was Apollo 14-17. Apollo 1 burned up during a test. They were man rated, yet much less reliable than the Falcon 9. No rocket is perfect.

    The rocket uses turbine pumps to push fuel and oxidizer to the engines.

    The Romans learned advanced mathematics from the Greeks, who had already proven that the square root of 2 was irrational. I think they had plenty of math to build an arch.

  11. Re:Slight pet peeve of mine-- on NASA's Cassini Captures Photos of Saturn's Rings In Unprecedented Detail (voanews.com) · · Score: 2

    Color cameras are just crippled cameras. Each pixel in the image is made from 4 pixels in the camera. One red, one blue and 2 green. The camera then balances the output to make the output pixel. With a monochrome camera, each pixel provides separate output. That way data is collected 4 times faster. When astronomers, both professional and amateur, create those wonderful color pictures of deep sky objects, they do it with filters and a monochrome camera. They will take many pictures to collect hours of black and white images to get all the detail. Then they may take separate red, green, and blue images to add the color. Or, they may use filters that take in the light of certain elements like hydrogen, oxygen and sulfur. They then use software to combine all that information into the final product.

    I was always a fan of Symantec. Their entire suite became a huge resource hog. But, it was always better in antivirus tests. Once I found out that Microsoft stops checking for viruses where the exploit has be fixed in Windows, that made sense. Defender just stopped checking for viruses that will do no harm to the system. Drops the overhead dramatically.

  16. Re:That is irrelevant to this discovery on Scientists Find 'Oldest Human Ancestor' -- A Big-Mouthed Sea Creature With No Anus (bbc.com) · · Score: 1

    The paper is not calling this a proto-deuterostome, it calls it a deuterostome. To fit the definition of deuterostome, the first hole evolves into the anus of all decedents. If that is not the case, the paper is using the wrong terminology.

  17. Re:Isn't that a myth? on Scientists Find 'Oldest Human Ancestor' -- A Big-Mouthed Sea Creature With No Anus (bbc.com) · · Score: 4, Informative

    This is the biological definition of deuterostomes. As the embryo changes from a mass of cells to an organized body, the mass starts to cup and folds around to form an internal cavity. This becomes the body cavity. The hole left eventually becomes the anus. The mouth forms later. All deuterostomes form this way till today, including all chordates/vertebrates and sea stars and related other sea creatures. Protostomes do the opposite, the initial hole becomes the mouth. These are the arthropods and mollusk and the like. It is not an evolutionary hold over, but the body forming process that continues to this day.

    I know this comes later in evolution, but doesn't the first orifice for the anus, and the second the mouth in a deuterostome? I realize this creature has only one opening, so it uses it for both. If so, it shouldn't be called a "big mouthed sea creature with no anus" but a "big anus sea creature with no mouth."
