During class today, I talked about tides and how there is a great deal of misinformation out there.
My favorite websites for the astronomical explanation of tides are:
- A rigorously correct but a tiny bit snarky treatment – it’s my favorite: Tidal Misconceptions by Dr. Donald E. Simanek
- One of the links from the page above is a much more mathematically rigorous treatment with equations and animations: Tides and centrifugal force by Paolo Sirtoli
- National Oceanic and Atmospheric Administration (NOAA) Ocean Service Education Tides and Water Levels page
- Dr. Sten Odenwald’s Ask an Astronomer :: 10 FAQ about Lunar Tides
The YouTube videos of the awesome spring and neap tides in Clovelly.
In class today (Wednesday), I showed some of the lunar landing footage available to we, denizens of the Internet, for FREE! NASA is a public entity and as such, happily will show us many awesome things and has given us the Apollo Lunar Surface Journal (ALSJ). Much of the text was written by former astronauts from the missions themselves and many of the best/crowd-favorite clips provide some context.
Whilst meandering the internet last summer looking for great astronaut videos to use in outreach, I came across this great website: Top 10: Videos From the Moon Landings (from How It Works Magazine). I’d already found some of them in browsing the COPIOUS video clips in the ALSJ but this website really does have some of the very best :) My favorites almost always involve the Apollo 17 mission it seems (this is a FANTASTIC Wikipedia page – check out the multimedia at the end!!)… But I suppose that one was the one with the geologist and he seems a bit more jovial than the others sometimes :)
In the end, don’t let anyone tell you we didn’t land on the Moon. You can find “Bad Astronomer” Dr. Phil Plait’s debunking here along with a page of several links to debunkers (and deniers!). You can find the Mythbusters episode debunking here (never mind – you have to find that yourself, they keep taking the versions I know down). You can find an excellent debunking website called clavius.org here.
