Mirror Physics and True Mirrors

I never heard of true mirrors until recently.  I find this video fascinating but hard to follow! It's from a science blog called Physics Girl. Here's the link: Physics Girl Another video from YouTube: I copied the instructions on how to make your own mirror: I haven't tried to make one myself yet.   Broken glass from dropping the mirrors can be dangerous. A homemade mirror will show a line down the center where the two mirrors touch.  For a perfect model I saw them selling for over $200! So much money for two mirrors attached together!

The Neapolitan Mastiff

"The Neapolitan Mastiff or Neo, comes from Italy, where once it was used as a gladiator dog in the bloody spectacles of the Coliseum. They were also used as war dogs by the Roman legion. Today, they are generally protectors of the home. Distinctive in appearance, the la rgest males can t op 200 lbs and are covered in loose, wrinkly skin with hanging jowls."    From  Top 10 Lists - Listverse

My Iron Deficiency Anemia

I'm having another spine operation to correct a "lump" which developed on the incision site from my first operation.  The "lump" is a pseudomeningocele. From Wikipedia: "A pseudomeningocele is an abnormal collection of cerebrospinal fluid (CSF) that communicates with the CSF space around the brain or spinal cord. In a pseudomeningocele, the fluid has no surrounding membrane but is contained in a cavity within the soft tissues." Anyway, while having my pre-op blood work they found that I have anemia.  It was a surprise to me because I have no symptoms. I thought the treatment would be easy. Take iron tablets 3 times a day.  But after spending a day on and off the toilet with painful black tar-like stools; I decided to stop taking the medication.  Maybe after my operation next week I might try 1 tablet a day. I found the chart above with some strange causes for anemia.  I can believe some of them but there are others that are just too muc

O.A.R. -Peace

I love the video.  It goes great with the music and lyrics.  Try full screen. O.A.R. - Peace I don't wanna fight no more I only wanna get to shore Baby don't slam the door tonight We ran another off the tracks  That's time we can't get back We can save tomorrow if we try Oh oh oh oh until we make this right Oh oh oh oh I won't say good night  I just wanna make you laugh I just wanna see that smile Babe we're only here, oh for a little while I just wanna hold you till we fall asleep  I want love, I want us, I want you, I want me, I want peace Everybody needs a place, somewhere that's warm and safe For shelter from this crazy world we're in But tonight I let the rain inside, I took away your place to hide I'm sorry that I made you cry again

Two Days Without Water

I get my water from a private well.  It needs a well pump and a well pressure tank to work. My well pressure tank finally died.  It must have been about 30 years old so I can't complain; except that it decided to die on some of the coldest snowy days in February.  July would have been much better. Luckily I know of a good contractor.  Eric came in the snow and spent the entire day replacing the tank. I had no idea how much going without water would be such an inconvenience. Using bottled water to drink is easy.  What's really bad is having to go without taking a shower.  You can wash your hands if you use the the water from a bottle.  You can take a "sponge bath".  It's just not the same. So I melted some snow in cooking pots to have more water to use for washing. That helped a little. What's the very worst part?  You can't flush the toilet! After one flush the tank is empty and won't flush again.  I used some melted snow and bottled
