Navigating to the Moon — Remembering the Apollo Sextant

The Apollo sextant was used in Earth and lunar orbit, as well as while en route between Earth and the Moon. It played different roles in each of those contexts: in orbit around Earth or the Moon, the sextant could be used to compute the spacecraft’s altitude and position; whereas in transit between Earth and the Moon, it could be used to compute the spacecraft’s attitude (orientation), position, and velocity. A proper attitude during the flight to and from the Moon was critical for accurate course corrections and burns to reach the Moon and correctly insert the spacecraft into the desired lunar orbit. The device was used repeatedly throughout the Apollo program across many phases of the missions, up to and including re-entry.

Pretty impressive advanced technology! Also shows how the basics will never be outdated.

The Day the Dinosaurs Died

A young paleontologist may have discovered a record of the most significant event in the history of life on Earth.

He recalled the moment of discovery. The first fossil he removed, earlier that summer, was a five-foot-long freshwater paddlefish. Paddlefish still live today; they have a long bony snout, with which they probe murky water in search of food. When DePalma took out the fossil, he found underneath it a tooth from a mosasaur, a giant carnivorous marine reptile. He wondered how a freshwater fish and a marine reptile could have ended up in the same place, on a riverbank at least several miles inland from the nearest sea. (At the time, a shallow body of water, called the Western Interior Seaway, ran from the proto-­Gulf of Mexico up through part of North America.) The next day, he found a two-foot-wide tail from another marine fish; it looked as if it had been violently ripped from the fish’s body. “If the fish is dead for any length of time, those tails decay and fall apart,” DePalma said. But this one was perfectly intact, “so I knew that it was transported at the time of death or around then.” Like the mosasaur tooth, it had somehow ended up miles inland from the sea of its origin. “When I found that, I thought, There’s no way, this can’t be right,” DePalma said. The discoveries hinted at an extraordinary conclusion that he wasn’t quite ready to accept. “I was ninety-eight per cent con­vinced at that point,” he said.

Fascinating.

Chuck Todd Devotes an Hour to Attacking a Strawman

The belief in human-caused warming exceeding a level that what would be relatively benign, and maybe even beneficial, is just that — a belief. It is not based upon known, established, and quantified scientific principles. It is based upon the assumption that natural climate change does not exist.

Got that. Let’s repeat:

It is based upon the assumption that natural climate change does not exist.

Hundreds of never-before-seen nuclear blast videos show terrifying explosions in the ocean and Nevada desert

The US government detonated hundreds of above-ground nuclear explosions from 1945 to 1963 — until the first nuclear test-ban treaty was signed. Now a team has rescued thousands of classified films that were kept in high-security storage.

There are several videos included in the article. Here’s the link to 497 other videos: LLNL Atmospheric Nuclear Tests

The 1911 Heat Wave Was So Deadly It Drove People Insane

Ice and electric fans were luxuries, air conditioning unknown. Pedestrians fainted from the stifling heat. At night, the streets were filled with exhausted mothers walking up and down, trying to comfort their crying babies. They feared leaving them in their beds, lest they fail to wake up.  One police officer described the night during the 1911 heat wave as a ‘giant wail.

This is before man was causing ‘global warming’ or ‘climate change’ by releasing CO2 into the atmosphere.

NASA confirms: In space, ‘reverse cowgirl’ and ‘doggystyle’ are the same thing

The same issue came up when the astronauts went with more exotic positions, such as “doggystyle” and “reverse cowgirl.”

“It was hard to decide what was going on. I mean, I got behind her, but we couldn’t decide which position we were trying.”

But is there video?

State to homeschoolers: Watching eclipse not educational

“In the nearly hour-long home visit, the assistant director told Hope that the trip that her family took to observe the solar eclipse wouldn’t be counted as school time. The school official also belittled her ability to educate her children, stating that even as a professional educator he wasn’t qualified to teach his own children at home,” the report said.

This ‘school official’ is human excrement. I AM qualified to teach anyone anything I know. This includes home schooling my kids, or any kids, through high school. I am a high school graduate. If you aren’t qualified to teach what you know, then your high school diploma is worthless and you should sue your school district.
