1/31/1868 Richards Theodore chemist His father was a painter and his mother a poet, in addition he was interested in music and science. He worked on determining with the greatest possible accuracy the atomic weights of elements.He advanced the theory of isotopes with his studies on lead. He worked with Meyer, Ostwald and Nernst. He died in 1928 at age 60.
1/31/1881 Langmuir Irving chemist worked under Nerst at Gottingen, discovered the use of inert gases to extend the life of a light bulb. He discovered an atomic hydrogen blowtorch that could reach temperatures of 6000 degrees. He invented high-vacuum tubes, he devised a theory of catalysis on platinum wires, he also worked on “rain making.” He died in 1957 at age 76.
1/31/1929 Mossbauer Rudolf physicist in 1958 he announced the Mossbauer effect. Atoms recoil as they emit gamma rays, the energy of the gamma ray depends in part on the amount of recoil. This is why gamma rays are emitted with a considerable spread in energy and wavelength. If a crystal takes up the recoil since it is so massive, it confines the wavelength to a very narrow spread. This is the Mossbauer effect. He died in 2011 at age 82.
This is the last one about puppies for a while, next month I will talk about dog tips for dogs that are about 6 months old. One last entry on the puppies. It is a good idea to keep the diet stable. If you are going to try new foods, do it gradually mixing about 10% of the new food with the old, then 25% then 50% etc. If the dog quits eating the food when you mix it, they probably don’t like the new food. I give my dog a taste of everything I eat, but I still have a top quality dog food out for it all the time. I know they say you shouldn’t do this, but I have never had an overweight dog nor have I ever had a chow hound.

Today is the birthday of Max Theiler, Born in 1899, He worked out the vaccine for Yellow Fever by passing the virus back and forth in mice then chickens. Got the Nobel prize in 1951 and had no academic degrees.
Plan the future of your dog. When it grows up and winter sets in, are you prepared to take it out for walks multiple times a day? Where will the dog stay all day while you are at work? Will you need a fenced in yard or play area? A lot of people have dogs but that doesn’t mean the dog has a very good life. Putting a dog outside on a chain all day is not only cruel to the dog, it is cruel to your neighbors and often against the law. Puppies are cute and a lot of fun, as are adult dogs, but adult dogs require attention and care. They still like to play and get exercise. Maybe a cat is a better option, if you can’t live up to the responsibility of a dog.
Channellock pliers are, Made in America. Always check the package, some of their tools are made in other countries.
1/29/1773 Mohs Friedrich mineralogist devised the Mohs scale in 1822. died in 1839 at age 66.
1/29/1838 Morley Edward chemist He worked on the relative weights of hydrogen and oxygen in the 1870s and collaborated with Michelson on the famous Michelson-Morley experiment. he died in 1923 at age 85.
