Is it fair to deceive humans in an unethical psychological experiment in order to receive new information? This is a question that I believe needs to be asked when one thinks of the Milgram experiment‚ a psychological study set up in the U.S in 1965. American psychologist Stanley Milgram held an experiment in order to see how severely ordinary human beings could knowingly cause harm to another human. This idea came about when he studied the holocaust in Germany in WWII‚ and then in the Nuremberg

that way if you believe in the power of change. Hydrogen fuel is that change for the automobiles of the future. Hydrogen has been used for decades‚ but mostly for commercial use. Each year‚ we get closer to removing the oil company’s choke hold on our wallets. It’s time to drive with a lighter purse and a cleaner environment and it’s time for hydrogen fuel. The two largest points of debate with hydrogen fuel are cost and production Hydrogen fuel is a cheaper alternative to our current source

IRON (METAL) Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole‚ forming much of Earth’s outer and inner core. It is the fourth most common element in the Earth’s crust. Iron’s very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars‚ Like other group 8 elements‚ iron

NAZI MEDICAL EXPERIMENTS During World War II‚ a number of German physicians conducted painful and often deadly experiments on thousands of concentration camp prisoners without their consent. Unethical medical experimentation carried out during the Third Reich may be divided into three categories. The first category consists of experiments aimed at facilitating the survival of Axis military personnel. The second category of experimentation aimed at developing and testing pharmaceuticals

HYDROGEN BONDING: Hydrogen bonding is a bonding type consisting of dipole and dispersion forces. A hydrogen bond is the attractive force between a hydrogen atom attached to a molecule and an atom of a different molecule. According to the Pauling scale of electro-negativities of the elements‚ it can be viewed that the three most electronegative elements in the periodical table are nitrogen‚ oxygen and fluorine. These are also called heteroatoms. The heteroatoms have a partial negative charge while

Hydrogen Fuel Cells There are many reasons to look for new cleaner forms of energy. Fossil fuels‚ being non-renewable‚ will eventually run out. Pollution from burning fossil fuels destroys our environment. Hydrogen fuel cells could be used many places where fossil fuels are currently being used. Using hydrogen as a form of energy can not only reduce our dependence on imported oil‚ but also benefit the environment by reducing emissions of greenhouse gases and pollutants that affect our air quality
