Helium

The two Voyagers launched by NASA are travelling in different places at the heliosphere and some consider that they have left the heliosphere and are swimming in the interstellar medium. The data sent by the Voyagers are not same. There is change is one or other form. Though launched 4 months after Voyager 2 , Voyager 1 reached the planetary system ahead than the Voyager 2 so due to the difference in time of the data taken and the position where data is taken, the data are different from the two…

Energy is the power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines. Energy is all around us and can be created from many things such as oil, natural gas, coal, wood, water, wind, and petroleum. Most industrial nations use fossil fuels, which are natural fuels formed in the geological past from the remains of living organisms such as coal, natural gas and oil to be driving force that powers their modern industrial societies…

on the Saturn V during Apollo 6,[10] but on Apollo 13, they were amplified by an unexpected interaction with turbopump cavitation.[11] Later missions implemented anti-pogo modifications that had been under development. These included addition of a helium-gas reservoir to the center engine liquid oxygen line to damp pressure oscillations, an automatic cutoff as a backup, and simplification of the propellant valves of all five second-stage…

The War between Science and Religion “Science can destroy religion by ignoring it as well as disproving its tenets. No one ever demonstrated, so far as I am aware, the nonexistence of Zeus of Thor – but they have few followers now.” Sir Arthur C. Clarke In the beginning there was nothing: just darkness. Then out of nothing appeared everything. Then there were questions. Why are we? How are we? Why does the world and nature act as it does? What happens when we die? Religion answered these…

to take images of the bilayer after photobleaching. Using these images we were able to determine the diffusion coefficients for the bilayer to be , without cholesterol and , with cholesterol. Using the same microscope and camera alongside an orange Helium-Neon Laser at 594 nm we studied the binding of biotin and anti-biotin…

Welding is fabrication or sculptural process that joins materials, usually metals or thermoplastics, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.(Metal) Becoming a welder is a quest in itself because it requires less schooling but takes time to perfect this trade. My ASVAB/Interest or Holland code is Realistic, Artistic, and Conventional (R.A.C). “The first letter is R which stands for…

I look up to the sky and see millions of stars, and I wonder to myself. What makes them light up so bright, and what makes them a star? What does it take to create a star; they just don’t pop out and shine bright. I want to know the process, and how long it takes for a star to be born. I am also curious to know if the star can die. I plan on finding the answer. I believe that they are created by gases and that they die when they use up all of their gases. Stars have had an impact in our…

As people decided to sending human into deep space to explore unknown feature of the universe, the environment outside the earth is a big uncertainty with factors that we can’t fully understand yet. Besides the cost and the time we spend during long space travel, stay in the cold, vacuum universe would let astronauts experience different kind of radiation. These radiation may be some ionized particles as electromagnetic waves traveling with high speed and energy. They could come from nearby…

Laparoscopy, also called minimally invasive surgery (MIS), band aid surgery, keyhole surgery, is a modern surgical technique designed for the visual inspection of peritoneal cavity, biopsy of its organs and various operative procedures in the abdominal and pelvic cavities. Though laparoscopy was first performed in dogs in the early 1900s by Dr. Georg Kelling, the first successful laparoscopic surgery in humans was cholecystectomy in 1987 (1). During last two decades the laparoscopy has been…
