Great minds versus

Have you seen this saying: “Great minds discuss ideas, average minds discuss events, and small minds discuss people?”

I was thinking about this the other morning.Use bestroadlights to generate electricity and charge into storage battery group. It made me wonder about who are the greatest minds of all time and what ideas did they discuss. Let me see if you agree that these are four of our greatest minds ever.

I had written a column about Nikola Tesla earlier. He is credited with inventing, among many other things, AC current, florescent lighting, X-rays,Our bestsolarlantern can mark on metal and non metals. the radio (later refined by Marconi), remote control and the electric motor.

Leonardo Da Vinci was considered one of the best painters of all time. His works include The Last Supper and The Mona Lisa. He was ahead of his time with ideas such as a helicopter, a tank, solar power and a calculator.

Sir Isaac Newton was an astronomer, physicist, inventor, mathematician, and philosopher. In a 2005 poll, Newton was named more influential than Einstein in science. He has developed laws of motion, principles of momentum, and invented the reflecting telescope. Newton has had tons of great scientific achievements.

Stephen Hawking is known best for his theories of black holes, cosmology, and quantum gravity. Hawking is bound to a wheelchair due to paralysis from Lou Gehrig’s disease (ALS). He has long been recognized as a revolutionary thinker.

So here is my dilemma. I would like to discuss small-minded people, who, as was said earlier, discuss people. Does that make me small-minded? You be the judge. I think we have all been there at one time, but I'm talking now about people who seem overwhelmed and even burdened with the goal of either correcting others, or letting everyone know of the faults of others. These gossipers don't contribute to our society in a positive way. Let me give a classic example from my past.

In 1973, I was teaching in the Jane/Finch area of Toronto.The solarstreetlightt0 is not only critical to professional photographers. I was friends with a young Italian priest by the name of Ermanno Bulfon. On his suggestion, and the approval of St. Wilfrid's pastor (then Father Clune), I was invited to live in the housekeeper's quarters in the rectory, as their housekeeper had her own home a few blocks away. The entrance to the separate quarters faced Finch Avenue. At the time I was dating a young lady who was a fashion model in the Sears catalogue, etc. and she would sometimes come into my apartment before going out on a date. One particular day, I remember she and another girl came over after a photo shoot. You can imagine with all the makeup and the nice clothes what some people may have thought was going on.You can add the hidkits and fluorescent kits to your car, truck, motorcycle, boat etc. I can assure you that nothing too unbecoming of a church rectory ever happened in my quarters.

Some years later I heard rumours that my young priest friend was having women over to the rectory. Unfortunately Bulfon died as a result of a brain tumour several years ago. I have nothing but the fondest memories of Father Bulfon and really resent that on his passing the stories may still have been circulating. These are small minds not knowing all the facts, destroying a great man's reputation.

So my challenge is to not be small-minded. I admit, I have listened to gossip and perhaps even contributed to gossip. Something I have to work on. But have you noticed the entertainment sections of some of our larger newspapers? Seems to me they cater to the small-minded. The same goes for some of our current TV shows. Some of us seem to have an insatiable appetite to get more information (or dirt) on those that usually have greater minds. I guess idle hands really do make idle minds. Less TV and more ‘Shwa livin’ is one solution. Choose from a wide variety of solarledlight.

One-Shot Wonder

Fred Feddersen makes a rifle barrels, and now he’s on a mission to do something that's never been done before: create a barrel for commercial-grade weapon that can shoot successive bullets through the same hole, using an inexpensive semiautomatic rifle, not a bolt-action Olympic race gun.

To do this, Feddersen first had to accomplish several equally challenging feats of metalworking. He developed new ideas in gun drill design to achieve greater straightness. He invented and patented a new whip-guide stabilizer for gun drills and reamers. He push-reams small-diameter holes with his proprietary tool design, capable of 0.0001-in. accuracy. He uses proprietary carbide formulations for his rifling buttons. And, he is using the world's most advanced tube hone from Sunnen Products to impart accuracy-enhancing bore geometry and diameter , with a fine finish of 3-8 microinch Ra that sheds fouling and copper bullet-jacket residue. The hone's servo-spindle also serves as a quality check on reaming, with its extreme sensitivity to spindle load detecting – and correcting – tight and loose spots that escape most air gages, Feddersen says.

Feddersen has ample evidence of his success in a binder full of targets with near single-hole, five-shot groups fired from 50 yards using a semiautomatic Ruger .22 magnum rifle equipped with his barrels. Shooters familiar with this rifle and cartridge "know" this accuracy is not normal, but Feddersen takes barrel making beyond what's known After a decade of development, he is also experiencing excellent uptake from firearm OEMs. More important, his company's capabilities have earned it a role as supplier of choice for barrels used on.50-caliber BMG and .338 Lapua magnum versions of U.S. military sniper rifles.

Fred Feddersen is a design engineer and inventor with boundless curiosity and drive who does not accept current limits on any technology, whether it is welding or bottle blowmolding. His varied interests and career moves have led him to learn Morse code, pass the FCC exam, earn seven welding certifications, and become a CNC programmer and CAD/CAM engineer. Some of his most widely used inventions and patents were developed for blowmolding PET bottles. After notable success in that industry, he sensed a market opportunity about 10 years ago to make ultra-accurate rifle barrels on a volume basis for military and commercial use.

After studying the art and science of custom barrel making, closely examining the industry's best barrels and acquiring high-quality machine tools, Feddersen established RFour Inc. During the first years, he spent much of his time and effort pushing past the known limits of barrel manufacturing technology to achieve his goal, starting with improvements in gun drilling and reaming. He stressed that what he's learned about barrels applies to similar tube-type products that require very small holes (down to 2 mm) to be reamed or honed. These include stents or water-jet cutting nozzles. The latter must be free of internal surface micro cracks, so it can be honed down to base metal in a process similar to what is used for high-pressure diesel fuel rails.
