Gravity is the strongest of the four known forces; electromagnetic, weak and strong nuclear forces which operate at the subatomic level but hold atoms and therefore our world together, and then gravity. In the past, we've been able to observe and measure the effects of gravity but could not detect it directly. Modern astronomy has now actually detected gravitational waves for the first time. Understanding the basic properties of gravity is the next great step in our understanding of our universe.

Jerry, There is a reason why one does not want to mix the gases in their tires and it is due to Dalton’s law, which is the statement that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual component gases. The partial pressure is the pressure that each gas would exert if it alone occupied the volume of the mixture at the same temperature.

In simple terms, each gas produces a specific pressure based on its temperature. In a mixture of gases, it means that the resulting pressure will be the sum of each of those gas's pressures. Because the tire is a confined space, those pressures will be the aggregate of the pressure of each of the gases in the tire.

Rongnongno, you hit a critical point when you began this conversation. More workers will get displaced as a result. Some will survive by being motivated enough to get retrain for other jobs, but a fair portion will not and will add to the growing numbers of people who join the ranks of the unemployable. I am sure this will rekindle the discussion for creating a minimum income for the nation. To some, especially the greedy wealthy (and I must state that not all wealthy people are greedy) and those already on the margin, this has and will seem like a crazy idea (what give money away?), when in reality it probably makes perfect sense if you think about the future of the nation. It will be for what people ‘need” to live, not for what they ‘want’, and there is a difference. Think of it this way, if you will, if people don’t have what they need, what is the incentive strive for a better life or to fight for the country, if and when it is necessary? It not only incentivizes people to defend the country, but a way of life we can all enjoy. As Marx warned what’s seems like long ago, when the growth of the people living in poverty (the proletariat) become so numerous and disenchanted with the way things are, they will revolt. I, for one, believe that in a nation as rich as this one, we should care for those left behind by the economic and social progress we strive for, if we don’t what will be the incentive to defend the nation?

The rant is over.

Yes, things are getting strange.

Did you ever hear of the Roadkill Cafe? It's a chain of restaurants that feature "roadkill" on the menu, although it's not really roadkill. What I'm getting to are the waitresses. They are intentionally insulting, and like eating dead animals found on the road, that's part of the "charm" of the place. We went to one in NH years ago.
