Titration A titration is a method of analysis that will allow you to determine the precise endpoint of a reaction and therefore the precise quantity of reactant in the titration flask. A buret is used to deliver the second reactant to the flask and an indicator or pH Meter is used to detect the endpoint of the reaction. Doing a Titration Begin by preparing your buret, as described on the buret page. Your buret ...

 What is the history of HIV, and when was HIV discovered?The history of the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) dates back to 1981, when homosexual men with symptoms of a disease that now are considered typical of AIDS were first described in Los Angeles and New York. The men had an unusual type of lung infection (pneumonia) called Pneumocystis carinii (now known ...

If you think of critical mass in terms of marbles, the tight formation of marbles represents critical mass and the three lone marbles stand in for neutrons. Fission Bomb DesignIn a fission bomb, the fuel must be kept in separate subcritical masses, which will not support fission, to prevent premature detonation. Critical mass is the minimum mass ...

Hiroshima Peace Memorial stands as a visible reminder of the day the Japanese city was bombed on Aug. 6, 1945. After that fateful day, the structure was the only thing still standing in the vicinity of the explosion. The first nuclear bomb meant to kill humans exploded over Hiroshima, Japan, on Aug. 6, 1945.

Cancer VirusesWorldwide, cancer viruses are estimated to cause 15 to 20 percent of all cancers in humans. Most viral infections however, do not lead to tumor formation as several factors influence the progression from viral infection to cancer development. The hepatitis B virus (shown above) is an example of a cancer causing virus that has been linked to liver cancer in people with chronic infections. Read MoreMore ...

Petroleum (L. petroleum, from Greek: petra (rock) + Latin: oleum (oil)[1]) or crude oil is a naturally occurring, flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface. A fossil fuel, it is formed when large quantities of dead organisms, usually zooplankton and algae, are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling. This latter stage comes after the studies of structural geology (at the reservoir scale), sedimentary basin analysis, reservoir characterization (mainly in ...

Polydactyly or polydactylism (from Ancient Greek πολύς (polus) "many" + δάκτυλος (daktulos) "finger"), also known as hyperdactyly, is a congenital physical anomaly in humans, dogs, and cats having supernumerary fingers or toes.[1] The extra digit is usually a small piece of soft tissue that can be removed. Occasionally it contains bone without joints; rarely it may be a complete, functioning digit. The extra digit ...

The photos of his hands and feet look like they were photoshopped to add an extra digit , but they weren't. Devender Harne was born with twelve fingers and thirteen toes. That seems like it would be pretty useful. It certainly helps him type faster. It may also earn him a place in the Guinness Book of World Records. (via J-Walk) ...
