“Movember” is not a typo, and neither is “Shave” in the title. In fact, November is celebrated worldwide as Movember, which is an annual, month-long event involving the growing of moustaches during this month.
The purpose of Movember is to raise awareness of Men’s health issues, such as prostate cancer and other male cancers; and about associated charities. The Movember Foundation runs the Movember charity event, housed at Movember.com. The goal of Movember is to “change the face of men’s health“. By encouraging men (or “Mo Bros”) to get involved, Movember aims to increase early cancer detection, diagnosis and effective treatments, and ultimately reduce the number of preventable deaths. Besides getting an annual check-up, the Movember Foundation encourages men to be aware of any family history of cancer, and to adopt a healthier lifestyle with exercise and good diet.
Movember moment started in Australia, when a group of young men in Adelaide, South Australia coined the term “Movember” and came up with the idea of growing moustaches for charity throughout the month of November. Interestingly, the idea of Movember and growing moustaches was born in a pub, over a few drinks. The Movember group started with 80 men from Adelaide and soon became a nation wide phenomenon. Since then “Movember Foundation” has since raised $174 million worldwide, after spreading to South Africa, Europe, and North America. In 2012, nearly 1.1 million Americans signed up to take part in Movember event, raising over $95 million.
“Shave the Date: Movember 1st” is the official start of Movember this year. It’s the day to shave down and get excited about the hairy month ahead. As the official Rules of Movember state, men must begin clean-shaven on the 1st of Movember and grow only a moustache for the 30 days of the month.
So remember to start this Movember with Shave the Date : Movember 1st!
As per “Movember United States” website:
“Mo Bros take action by changing their appearance by growing a moustache for the 30 days of Movember, to spark conversation and raise funds. Mo Sistas commit to supporting the men in their lives while helping to promote men’s health.”
Relevant to Movember, a few words about the careful diet that may enable some control on probability of reducing Prostate Cancer. Some of the studies show that Trans fats, saturated fats, and carbohydrates may be associated with an increased risk. The studies also suggest that Omega-3 fatty acids may result in some benefit. Vitamin supplements seem to have no effect and in fact some supplements may increase the risk. High calcium intake has been linked to advanced prostate cancer. Consuming fish may lower prostate cancer deaths but does not seem to affect its occurrence. Some evidence supports lower rates of prostate cancer with a vegetarian diet. There is some tentative evidence for foods containing lycopene and selenium. Diets rich in cruciferous vegetables, soy, beans and other legumes may be associated with a lower risk of prostate cancer, especially more advanced cancers. Regular exercise, good healthy food and better weight control reportedly helps in reducing prostate cancer.
So what are you waiting for?
Join hands with MO Bros, and start to grow MOs in the Month of Movember.
Have a great Movember, MO Bros and MO Sistas!

On 100th Birthday of Hedy Lamarr, Most Beautiful Hollywood Actress & Visionary Inventor of Wireless Communication……
We respectfully salute Hedy Lamarr, for her amazing invention of Wireless Communication, and her great contributions to Science and Motion Pictures industry, on this special occasion of her 100th Birthday, on November 9, 2014.
Alles Gute zum Geburtstag, Hedy Lamarr!
Happy Birthday, Hedy Lamarr!
Our Best wishes to all Followers and Readers.
Massachusetts, Thursday, October 30, 2014.
Mathematically talented, Hedy Lamarr and music composer George Antheil invented an early technique for spread spectrum communications and frequency hopping. This invention laid a solid foundation that is absolutely necessary for wireless communication from the pre-computer age to the present day. We couldn’t have used Wi-Fi, cell phones, smart phones, iPod and iPad etc without the genius concept and technology conceived by Hedy Lamarr, the genius inventor.
Hollywood’s most beautiful legendary actress and also the brilliant inventor of wireless communication, Hedy Lamarr, was born in Austria, on November 9, 1914. Hedy Lamarr became famous as an American actress, but she was also a brilliant physicist and talented mathematician. She was very well-known for her stunningly exceptional beauty, and was often considered “the most beautiful woman in the world” – with “strikingly dark exotic looks” as described during 1940’s by Max Reinhardt, famous Austrian-American Film and Stage Director, who had taught acting to Hedy Lamarr in Berlin.
Hedy Lamarr was born Hedwig Eva Maria Kiesler in Vienna, Austria, as the only child in a wealthy Austrian family, nearly 100 years ago. Hedy Kiesler was mathematically inclined since childhood, and spent almost every evening studying and working on her inventions after her daily routine as Hedy Lamarr, an actress from Hollywood. Hedy’s life story was surely stranger than any fiction or the stories used in Hollywood movies. Nonetheless, what amazes many scientists, even today, is the fact that Hedy was well ahead in time in regards to her invention of secret wireless communication (US Patent # 2,292,387, granted on August 11, 1942). With her strong dislike towards Hitler and World War II, Hedy presented her invention, disclosing the novel concept of frequency-hopping secret wireless communication, to the U.S. Navy. Her intended application was to make radio-guided torpedoes that Germans will not be able to either detect or jam, thus bringing the war to an end with victory to USA. However, U.S. Navy treated Hedy’s invention with negativity and skepticism, and did not use it at all during World War II. Hedy was surely ahead in time, at that time; because exactly twenty years later (and three years after the expiry of US Patent), Hedy’s invention was used successfully by U.S. military ships during the blockade of Cuba in 1962. Since the turn of 20th century till to date, Hedy’s frequency-hopping wireless communication invention has become the solid foundation for latest spread-spectrum communication technology, which is implemented in cell phones, cordless phones, Bluetooth, COFDM, Wi-Fi, and GPS communications.
I have provided below the images of drawings and relevant text from the front page of Hedy Lamarr’s granted US Patent:
“Secret Communication System“
Now few words about Hedy Lamarr’s inventive concept and its reducing to practice as demonstrated in her patent: The concept of Radio Control was not at all novel even then, although Hedy’s frequency-hopping strategy was. Hedy’s co-inventor, for her invention on wireless communication using frequency-hopping, was George Antheil, American music composer and Hedy’s neighbor in Hollywood. Hedy Lamarr’s novel inventive concept was complemented by Antheil’s innovative contribution leading to the device that could effectively achieve the synchronization in radio control by frequency-hopping. Lamarr and Antheil proposed that rapid changes in radio frequencies could be coördinated the way Antheil had previously coördinated the sixteen synchronized player pianos in his Ballet Méanique. Their original invention used slotted paper rolls similar to player-piano rolls to synchronize the frequency changes in transmitter and receiver, and it even called for exactly eighty-eight frequencies, the number of keys on a piano. The schematic above, as presented by Hedy Lamarr and George Antheil in the US patent, shows the synchronization device and in sync coordination of frequency-hopping. Any scientist or inventor should find this invention totally fascinating, for it involves the creativity and meeting of minds of two experts – from distant and distinct disciplines.
Hedy Lamarr and George Antheil, after being neglected by the U.S. Navy, did not pursue their invention further. However in 1957, the concept was picked up by engineers at the Sylvania Electronic Systems Division, New York. Their prototype involved electronics and not piano rolls, and ultimately became the basic tool for secured military communications, and was installed on ships sent to blockade Cuba in 1962. Subsequent patents in frequency changing and modern spread-spectrum communication technology based devices, always reference to the Lamarr-Antheil patent (US # 2,292,387) as the basis of their new inventions – even today. Hence Hedy Lamarr is considered as the “Wireless Goddess“, because of her significant pioneering research and invention contribution in the field of wireless communication.
Hedy Lamarr was surely the most beautiful woman in the world by day, and the genius inventor by night. Hedy was the Wireless Goddess on Earth – with unique and amazing combination of Beauty & Brains. May God rest her soul in peace.

Here is an excerpt exploring Chaos, Endurance and Beauty, from Quotes.net
“Creation and cultivation of Beauty doesn’t happen without tremendous Endurance. True Beauty is often emerged out of Chaos and Turbulence. Look at the eruptions of Volcanoes and shaking of Earth that give birth to beautiful mountains and scenic lakes. Think of those amazingly attractive Stalactites formed only after continuous erosion by slow dripping water. Something far superior, magnificent, better and beautiful always appears out of otherwise ordinary – only after enduring the colossal Chaos, frightening Fury, traumatizing Turbulence and disturbing Disorder within the stagnant Status Quo. That’s the reality of life! So, accept and endure the changes, no matter how chaotic, stormy and irrational they may seem to you today. You are chosen by Supreme Powers to Create and Cultivate the Beauty, something that never existed before – only through your exceptional Endurance. And I am sure that you will, my friend, pass this test with flying colors. You’ve done it before, and you’ll do it again. Go on, and break a leg!“

You can always opt to “go with the flow” to follow what others and society norms dictate to you, or you can stand firm with your values to bring about a differentiating change in the world that would make it a better place than ever before. Be the Change Ambassador, and importantly, be the Change that you want to see in the world. In my view, one should strive to become a Thermostat rather than a Thermometer, because our world needs more Thermostats than Thermometers.”

In my view, it’s fascinating to understand how the word “Nylon” was invented, i.e. the Etymology behind “Nylon”. The term “Nylon” was coined by E.I. du Pont & de Nemours Company on October 7, 1938, but the origin of “Nylon” was disclosed 40-years later by the company in a 1978 publication (Context, vol. 7, no. 2, 1978). Per this 1978 article, the name “Nylon” was originally intended to be “No-Run” (“run” meaning “unravel”). It was later modified to avoid making an unjustified claim, since the nylon products were not really run-proof. The vowels were strategically swapped to create an anagram “Nuron”, which was later changed to “Nilon” “to make it sound less like a nerve tonic”. And for clarity in pronunciation, the “i” was smartly changed to “y”.
Thus the great “miracle fiber” and its name “Nylon” were born seventy-six years ago, and our world was never the same again.
Our respectful salute to Nylon, and the brilliant inventor Dr. Wallace Hume Carothers, on 76th Birthday of Nylon.
Massachusetts, Monday Night, October 27, 2014.
Here is some scientific info on Nylon, starting with the image of the Nylon Patent below – by inventor W.H. Carothers.
From Polymer Chemistry perspective, Nylons are, in essence, the condensation copolymers formed by reacting equimolar proportions of an organic diamine and an organic dicarboxylic acid, so that amides are formed at both ends of each monomer unit. This is very similar and analogous to the natural process that occurs in our bodies leading to polyamide proteins and polypeptide biopolymers.
The most commonly known and used nylon is nylon 6-6. The nomenclature and 6-6 refers to the fact that the diamine (hexamethylene diamine, IUPAC name: hexane-1,6-diamine) and the diacid (adipic acid, IUPAC name: hexanedioic acid) each donate 6 carbons to the polymer chain, hence the name Nylon 6-6. As with other regular copolymers like polyesters and polyurethanes, the “repeating unit” consists of one of each monomer, so that they alternate in the chain. Since each monomer in this copolymer has the same reactive group on both ends, the direction of the amide bond reverses between each monomer, unlike natural polyamide proteins which have overall directionality: C terminal → N terminal.
At du Pont, in early 1930’s, the research team led by Dr. Wallace Carothers had focused their efforts to create a synthetic fiber that would replace silk. This was because Japan was the main source of silk for USA, and the trade relations between the USA and Japan were breaking apart at that time.
By 1934, Wallace Carothers had made significant strides towards creating a synthetic silk by combining the chemicals, hexamethylene diamine and adipic acid to create a novel fiber formed by the condensation polymerization process, producing only water as a byproduct. Dr. Wallace Carothers refined the process to create stronger fibers by designing the reactors and chemistry so that the by-product water was distilled and removed from the process immediately as it was formed, thus making for resultant fibers amazingly stronger.
The general reaction for Nylon formation is shown below:
According to E.I. du Pont de Nemours & Company representative (1938 Press Interview) :
“Nylon emerged from research on polymers, very large molecules with repeating chemical structures, that Dr. Wallace Carothers and his colleagues conducted in the early 1930s at DuPont’s Experimental Station. In April 1930, a lab assistant working with esters – compounds which yield an acid and an alcohol or phenol in reaction with water – discovered a very strong polymer that could be drawn into a fiber. This polyester fiber had a low melting point, however. Carothers changed course and began working with amides, which were derived from ammonia. In 1935, Carothers found a strong polyamide fiber that stood up well to both heat and solvents. He evaluated more than 100 different polyamides before choosing one [nylon] for development.”
According to a 1938 article in Fortune Magazine:
“Nylon breaks the basic elements like nitrogen and carbon out of coal, air and water to create a completely new molecular structure of its own. It flouts Solomon. It is an entirely new arrangement of matter under the sun, and the first completely new synthetic fiber made by man. In over four thousand years, textiles have seen only three basic developments aside from mechanical mass production: mercerized cotton, synthetic dyes and rayon. Nylon is a fourth.”
With specialization in Chemical Engineering and concentration in Polymer Science at B.S, M.S. and Ph.D. levels, I am always fascinated by such amazing inventions and awesome applications of polymers, which have indeed changed the face of our modern world for better, in my view. I do hope that our Readers & Followers also find this information interesting, insightful and inspirational, as much as I do.
Keep your creative & inventive juices flowing!

“We, as Humans, are distinct and unique in our ability to dream, and then strive to transform those Dreams into reality. The Dreams at night, seen with eyes wide shut, are nothing but illusions created by electronic impulses and waves within our brain and central nervous system. On the contrary, the Dreams seen in broad daylight, with our eyes wide open, are the most important ones, because we can pursue those diligently with total focus from our heart and mind, and soon make them come true .
