Science Facts

There are only 5 countries in the world that still use Fahrenheit to measure temperature, the Bahamas, Belize, the Cayman Islands, Palau, and the United States.


American’s are stubborn and will often argue that their way is the best no matter what. For example, the Fahrenheit scale is still used for temperature despite it not making total sense as a temperature scale.

Once upon a time Fahrenheit was used by almost all English speaking countries, but in the 1960’s and 70’s most of these countries switched over to Celsius, with the United States being the most noticeable exception.

Today, only five countries, including the United States, use the Fahrenheit scale. The Bahamas, Belize, the Cayman Islands, Palau, and the United States and associated territories (Puerto Rico, Guam and the U.S. Virgin Islands) use the scale for every day applications, though the scientific community around the world uses either Celsius of Kelvin. Canada sometimes uses Fahrenheit, but the official temperature scale is Celsius.

Celsius is now considered the international standard for measuring temperature. It’s likely that one day in the future the remaining Fahrenheit-loyal countries will switch over to this scale. Surely once the United States changes the others would follow suit.

The plants used to make beer and marijuana are in the same botanical family!


Believe it or not you can pretty much say that both these plants are family!Cannabaceae is the scientific name that is given to this family of plants which include more de 170 species grouped in about 11 genera.

The Cannabacea family includes many plants, in which Cannabis (hemp/weed), Humulus (hops) and Celtis (hackberries) are included. And many of these plants have been used for ritual/medicinal purposes in China since 494 B.C!

Hop is currently used in the production of beer because of it's aromatic substances, while different subspecies of hemp are cultivated for the production of fiber, as a source of cheap oil, for the nutritious seeds or for medical cannabis!

Einstein made a refrigerator that required no electricity and had no moving parts


In the 1920s there were news reports about a Berlin family being killed when a seal in their refrigerator broke and leaked toxic fumes into their home.

This inspired the one and only Albert Einstein to design a refrigerator that didn't use any moving parts, thinking that eliminating any moving parts would also eliminate the possibility of a seal breaking.

Einstein worked with his former student Le Szilrd on the fridge from 1926-33, and based the design on a similar invention a few years earlier by a couple of Swedish investors.

The refrigeration cycle uses ammonia pressure-equalizing fluid, butane refrigerant, and water absorbing fluid, has no moving parts, and does not require electricity to operate, needing only a heat source, e.g. a small gas burner or electric heating element or even solar energy.

Although named after Einstein, it's likely that Szilrd did most of the actual inventing while Einstein consulted and did most of the patent work (he had worked in a patent office earlier in his life).

Some awesome lists!

Grand Central Terminal in New York has a room where people can whisper to each other 50 feet apart!


In this famous NYC landmark, there's a room called the Whispering Gallery. The reason for this name is that the shape of the room gives it an interesting acoustic feature. People who visit this room can stand in diagonal corners of the 50-foot wide chamber and whisper to one another. They can hear each other because the room is arched, and the sound carries through the ceiling.

People who can't wear latex gloves may not be able to eat a kiwi!


My award for the the least things likely to be related, but somehow are, is the allergic reaction between latex gloves and fruit.

Though it's one of the more common allergies you'll find, which is why nearly every doctor, food handler and TSA agent may question you about it, it's hard to believe that it would impede on a persons ability to eat a kiwi!

The allergy occurs when after repeated exposure to products containing natural rubber latex, so the more you use it the less immune to the allergy you'll be.

Mucus membranes may absorb the latex proteins which causes the body to produce antibodies that react with them, causing the allergy to surface. But what's that have to do with fruit?

People suffering from a latex allergy are susceptible to being allergic to a number of different plant products, normally fruit. This is known as the aptly named latex-fruit syndrome.

Fruits and seeds that can flare up the allergy include bananas, pineapples, avocados, chestnuts, kiwis, mangoes, passionfruit, figs, strawberries and soy. Most, but not all of these fruits contain the naturally occurring latex, which explains why it can cause an allergic reaction.
