Just my video of the Red Blood Moon lunar eclipse last April 15, 2014 at 12:00 midnight.
This was shot with a hand held Canon Vixia HFR40, with 53X Zoom (32X Optical Zoom). No tripod so it is a bit unstable.
Also taken in the background supposed to be Mars. If you are looking at this just a few minutes after this was uploaded, the video might still be processing on YouTube so it may be a bit blurry.
What actually makes the moon red is the same reason that makes the sky red during sunset and sunrise, it is explained near the end of this blog post. Since the sun’s rays passes by the earths atmosphere, the sunlight cast on the moon now appears reddish.
Just another Excel exercise, displaying electronic configuration. All you need to enter is the atomic number (which is also the number of electrons in the atomic state of an element) Nothing really special, just some series of if statements and some text formatting.

My daughter was working on some match assignment solving algebraic equations but instead of doing the usual transposition stuff, she was solving it in a matrix setting them up in row Echelon form. Something even I needed to review a bit to refresh my memory how it is done.
She then asked me if Excel can solve this to double check. And I said yes and no. There is no automatic way to show the row Echelon form of the matrix but I can certainly make some way to display it. So challenge accepted.
If you need to review yourself on the row Echelon form, I found this video to be useful.
If you need an MS Excel file that can solve 2 or 3 equations with 2 or 3 unknown variables respectively in matrices using the row Echelon form and needs to see the complete solution, you can try this file I’ve created. If you find this useful, you are free to use an distribute as long as you mention it was made by me, and link back to this page. Enjoy! Download it here: Row-Echelon-Form
Five employees at the Wild Fowl Publishing Company each come to work by a different one of five means: car, railroad, subway, and walking. They hold these positions at the company: art director, editor, publisher, receptionist, and secretary. Two of them are men named Finch and Marten, while three of them are women named Fulmer, Gannet, and Hawk. From the information given, determine the position held by each person as well as the means by which each one gets to work each day.
Neither of the men walk to work but one is the art director and the other is not the publisher or secretary.
The publisher is named Hawk or Fulmer and none of these takes the railroad or a car.
Mr. Finch does not come by railroad and he is not editor.
The female receptionist is not named Fulmer and neither of these two walks to work.
I was about to re-share a photo posted by When In Manila on Facebook, when a friend of mine here in the US saw it. The image had everything written English, except for one word, which was Epal. I had to explain it and gave the etymology of the word. And I decided to blog about it’s etymology.
What is Epal?
Filipinos have this weird way of turning some words into Filipino slang words by flipping the order of syllables, or flipping the order of sounds, or flipping the order of some letters or all letters. Where that method of creating slang words came from, I don’t know.
Looking at the word epal, this originally started with the Tagalog word for paper, which is papel. When you flip the two vowels, it turns into pepal, and after saying it over and over by various people, for some reason, the first “p” got dropped and turned into epal.
So probably many of you have heard tonight May 5, 2012) is the night when the moon should appear larger and brighter than it normally is. I can definitely see that it is indeed brighter. But seeing the moon to be larger would not be that easy to notice. According to the smart science people (you know astronomers, NASA people, Wikipedia updaters and stuff in news results), the moon will appear 14% larger. C’mon, would you even notice that?
