Celestron Digital Microscope!

I got my brand new Celestron digital microscope yesterday, only to find that it was broken!!! I quickly boxed it back up and drove 90 miles, each way, back to the third party who actually sent it to me. They replaced it and I returned!

In this video you will see:

A Fruit Fly!
Baker’s Yeast!
Baker’s Yeast Baby Buds!

The microscope has magnification from 40x to 1600x and a 3.5″ LCD screen! Super fun!!!

I am VERY MUCH NOT a biologist! I took a few classes years ago, but that’s it. This is a toy for fun… and for a special project coming up.

Please stay tuned for more videos!

Uranium! Uranium! Uranium!

A marvelous and amazing element!

Uranium 238 Decay Chain

Thorium 234
Protactinium 234m

Thorium 230
Radium 226
Radon 222
Polonium 214

Radiation and Uranium are amazing and powerful.

Like many of natures most powerful creations, Uranium is dangerous and must be treated with respect. Never expose children, pets, or your bare hands to Uranium. If you should ever touch a Uranium sample, always wash your hands carefully.

Remember, distance, time, and shielding, and hand washing are your friends.

As always, don’t try this at home

Abstract
Radioactive fallout from the triple reactor disaster at the Fukushima Daiichi Nuclear Power Station, following a magnitude 9.0 earthquake and subsequent tsunami, is readily observed in soil samples collected from Japan, well beyond the exclusion zone. Samples from three regions, approximately 210 km, 550 km, and 1060 km from the Fukushima Daiichi Nuclear Power Station, were tested for gross gamma activity and radio-isotopic composition. The primary isotopes of focus were the most commonly detected radio-isotopes of Cesium, 134 Cs and 137 Cs.

Note: Another individual should be listed as a co-contributor, given their important role in providing material from Japan for testing, but their name has been left out for purposes of anonymity. To that person, go my deepest thanks.
