It appears likely that crude hydrofluoric acid was first prepared by an unknown English glassworker in In the Swedish chemist Carl Wilhelm Scheele obtained hydrofluoric acid in an impure state by heating fluorspar with concentrated sulfuric acid in a glass retort, which was greatly corroded by the product; as a result, vessels made of metal were used in subsequent experiments with the substance. Fluorspar was then recognized to be calcium fluoride. The isolation of fluorine was for a long time one of the chief unsolved problems in inorganic chemistry , and it was not until that the French chemist Henri Moissan prepared the element by electrolyzing a solution of potassium hydrogen fluoride in hydrogen fluoride. He received the Nobel Prize for Chemistry for isolating fluorine. The difficulty in handling the element and its toxic properties contributed to the slow progress in fluorine chemistry. Indeed, up to the time of World War II the element appeared to be a laboratory curiosity.

Controversy[ edit ] Anthropologist Helen Fisher in What happens in the dating world can reflect larger currents within popular culture. For example, when the book The Rules appeared, it touched off media controversy about how men and women should relate to each other, with different positions taken by New York Times columnist Maureen Dowd [58] and British writer Kira Cochrane of The Guardian. Sara McCorquodale suggests that women meeting strangers on dates meet initially in busy public places, share details of upcoming dates with friends or family so they know where they’ll be and who they’ll be with, avoid revealing one’s surname or address, and conducting searches on them on the Internet prior to the date.

Don’t leave drinks unattended; have an exit plan if things go badly; and ask a friend to call you on your cell phone an hour into the date to ask how it’s going. If you explain beautifully, a woman does not look to see whether you are handsome or not — but listens more, so you can win her heart.

You like him, you like his friends, you like his moves in the bedroom. You wonder if he could be husband material. Then he sits you down and tells you that he has bipolar disorder. You find yourself unsure about whether or not your courtship should continue. Chances are, we either know how to handle it, or we are working on it. We Are Going To Need To Talk About Our Feelings People with mood disorders — bipolar, depression, borderline personality, anxiety and others — have learned that holding in our feelings is bad.

It makes us feel very intense negative feelings, and they are usually about ourselves. Moreover, when we feel bad, we have bad thoughts and might want to do bad things, like polish off a whole bottle of liquor, call up our ex, or get behind the wheel while in an agitated state. To ensure that we do not end up drunk dialing someone, or worse, we have to make sure our feelings do not get the best of us.

So we have to talk.

Click for larger view The above photograph shows Ron London and Bill Mottern setting up their low power x-ray machine, the same device that was at least in part responsible for the seizing of all of STURP’s equipment by Italian customs upon its arrival in Italy back in The wooden crate that housed the x-ray machine had a radiation sticker on the outside, and that apparently raised enough concern to cause the customs officials to seize everything and refuse to release it upon our arrival.

We arrived a week prior to the scheduled start of our examination while the Shroud was still on public display in order to unpack, set up and calibrate all our instruments and equipment so we would be fully prepared when the Shroud was brought to us. Unfortunately, it took five and a half days before the equipment was finally released so we had to work around the clock for the remaining 36 hours to prepare everything for our testing.
