idea of alien life is incorrect. Some take the concept of believing overboard‚ and others try to justify their disbelief by stating that most who believe are conspiracy theorists. Are aliens real‚ though? Since the universe is so expansive‚ why wouldn’t they exist? 6EQUJ5‚ also known as the Wow! signal‚ could have potentially come from extraterrestrial life force attempting to contact us. On August 15‚ 1977‚ at 11:16 PM‚ an Ohio radio telescope detected a single pulse of radiation coming from the constellation

Is It So Safe to Use Nuclear Energy? The fragile environment of our planet is now under threat. Carbon fuels such as coal and oil are running out and their emissions are destroying the ecosystem. To prevent the harmful effect on the environment‚ Dr Symonds discussed his view that nuclear power is the best affordable way to protect the nature of the Earth. Although the facts introduced at the conference were quite persuasive‚ there are some points to argue. There was a statement in which Dr Symonds

PEACEFUL USES OF NUCLEAR ENERGY “I lose my temper but it’s all over in a minute.” said the Student. “So is the Nuclear Bomb. But think of the damage it produces.” Teacher replied. Above mentioned quote confirms that we have always weighed nuclear energy with the destruction it causes. Thanks to the unique invention of nuclear energy‚ i.e. Nuclear Bomb. On hearing the word ‘Nuclear’ the only thing that comes to our mind is havoc and disaster mainly due to some unfortunate incidents such

Diversity exists. How could you be oblivious to it? Unfortunately‚ even though there is a visual aspect of diversity‚ not everyone can grasp the concept of diversity. The concept of diversity embraces respect and acceptance within our culture. There are so many dimensions of diversity‚ which include race‚ ethnicity‚ age‚ physical appearance‚ sexual orientation‚ and‚ but not limited to beliefs. Physically you can see the difference‚ but morally is it accepted by everyone? There are so many different

HC2O4−. A salt with this anion is sometimes called an acid oxalate‚ monobasic oxalate‚ or hydrogen oxalate. The equilibrium constant (Ka) for loss of the first proton is 5.37×10−2 (pKa = 1.27). The loss of the second proton‚ which yields the oxalate ion has an equilibrium constant of 5.25×10−5 (pKa = 4.28). These values imply that‚ in solutions with neutral pH‚ there is no oxalic acid‚ and only trace amounts of hydrogen oxalate.[1] The literature is often unclear on the distinction between H2C2O4‚
