Nose Facts

Did you know we all have four nostrils? We have two you can see, two you can’t. This discovery came from watching how fish breathe. Fish get their oxygen from water, most of them have two pair of nostrils, a forward facing set for letting water in and two for letting water out.

Our other two nostrils, migrated toward the back of the head, to become internal nostrils called ‘choannae’ – Greek for ‘funnels’. They connect to the throat and allow us to breathe through our noses.

Wrong Way Corrigan

We have all seen football players running the wrong way on the field, and some announcer will refer to the unfortunate player as Wrong Way Corrigan.

The original ‘Wrong Way’ was not a football player; he was Douglas Corrigan, unemployed airplane mechanic. It was on a foggy day in 1938, that Douglas left Floyd Bennett Field in New York, supposedly headed for Los Angeles. He landed his monoplane about 28 hours later in Ireland at Dublin’s Baldonnel Field. He had originally been denied a flight plan to Ireland and some think he did it on purpose, because he was of Irish descent.

Corrigan made the 3,150-mile flight without benefit of a radio or navigational equipment other than a compass. His explanation for the monumental mistake was that he was following the wrong end of the compass needle.

He was welcomed home as a hero with a ticker tape parade and known became Wrong Way Corrigan.

Wordology, Sport

Speaking of sports, the word sport was formed as an abbreviated form of disport. It first appears in a Middle English romance called Ipomadon in about 1440, 150 years before Shakespeare.

Disport derives from Anglo Norman desporter "to carry away" or, metaphorically, "to divert, entertain", formed from des "apart" and porter "carry". The word originally referred to "amusement". It did not gain its modern use until the 19th century.

Where Water Does Not Mix

There is a place in the Gulf of Alaska where two oceans meet but do not mix. Fresh water glaciers melted and flowed to join the ocean water, but because of the difference in the salinity and densities of these two water bodies, a surface tension developed between them that acts like a thin wall which prevents them from mixing. The boundary between the two is outlined by a thin layer of foam.

According to scientists, given enough time, the differences between these two bodies will disappear and they will merge together.

Bugs and Pain

Bugs may be a pain to us, but they feel no pain. Pain is officially defined as, "An unpleasant sensory and emotional experience associated with actual or potential tissue damage". It is experienced differently by each person and organism. Because of this it is extremely difficult to describe just how an animal experiences pain.

To study how an animal experiences pain, argument-by-analogy is applied. This means if the animal reacts in a similar way to how we would, we believe they are experiencing pain. An example might be if a dog is pricked with a pin and runs away, as a human would.

Insects have no capacity to feel pain. Nociceptors are what carry the feeling of pain to the brain. These are essential to experience pain, yet insects and crustaceans have never been found to have any nociceptors. This means most of these animals are unable to feel any sort of pain. Most insects do not possess nociceptors. I knew when I squished them they were not yelling.

Enlightening Idea

A multicolored interactive night light that comes with removable glow balls. The Glo Nightlight's balls will glow for 30 minutes, fading out while changing color. If you place the balls back to its place, they will start glowing again. The base is designed to charge the balls and they will not get warm or break.

It has three stems each holding a glowing ball. The base charges the balls up so at night, you can remove them and place them anywhere a little light is needed. It is 8.2 x 8.5 x 9.8-inch, made of BPA-free, Phthalate-free, PVC-free and includes a 9v power adapter and the low energy LED base. Cost is about $80 on the web.

Wordology, Buttload

A buttload is a real unit of measurement or unit of volume that is used for wines, ales, ciders, and other alcoholic beverages.

A butt is defined to be 2 hogsheads, which in the US is 63 gallons, so a butt is 126 gallons. A hogshead (corruption of the word oxhead) traditionally was two barrels and a hogshead of beer or ale is 54 gallons.

This has no relation to boatload, which is "the cargo that a vessel carries or is capable of carrying". A boatload might be about 54,107,280 gallons. It should also not be confused with butt that is a target for practicing archery, a part of the anatomy, or any other of the many definitions for butt.

Obsidian Knives for Surgery

Obsidian is a type of volcanic glass that has an extremely sharp edge when filed down. Some of the finest examples of blades made out of obsidian were discovered in Mesoamerica over 2,500 years ago. Dr. Don Crabtree re-discovered the ancient technology about twelve years ago, and along with other surgeons, believes there might be a place for obsidian blades in current medicine. Blades produced by Dr. Crabtree have been used in experimental microsurgery with excellent results.

The prismatic glass blade is infinitely sharper than a honed steel edge, and these blades can be produced in a wide variety of shapes and sizes. When used in experimental surgeries on animals, the blades yield comparable and even better healing than cuts made with traditional scalpels.

Why Milk is White

Milk is 87% water and 13% solids. It consists of about 5 percent lactose, 3.7 percent fats and 3.5 percent proteins. Casein is the most common protein and makes up about 80% of the proteins in milk. Also, casein's molecular structure is very similar to that of gluten. This is why many gluten free diets also are casein-free. It is the combination of casein and fats that give milk its color.

The color white results from all the wavelengths of visible light being reflected into the eye. Casein and certain fats reflect wide ranges of wavelengths, causing milk to appear white. Fat free milk appears a bit bluish due to reduction of fats reflecting light.

The pasteurization process that kills microorganisms in milk, also destroys the Vitamin C content, as well as significantly diminishes various other health benefits of milk.
