The purpose of this experiment was to use aldol condensation methods to synthesize colored cyclopentadienone and then UV/VIS spectrophotometry to characterize the dienone structure synthesized. The information gathered from the UV/VIS analysis was then compared to a computer model of the desired product to analyze the optimal 3D structure of the dienone. The base catalyzed condensation reaction was used to form the product for analysis, followed by vacuum filtration to recover the product. Both…

We’ve been listening for alien signals for several decades, though the silence has led as many to wonder if we are listening for the right things as those wondering if there are any aliens at all. What many fail to understand is how many signals a civilization like ours produces that are lost to the background noise before anyone outside our system would hear it, much less what they might learn if they were able to pick up our signals? What signals would an alien civilization detect? And what…

The first modern human fossils found in Western Europe were those from the archaic species Cro-Magnon. These fossils were discovered in March of the year 1868, near the village of Les Eyzies in southwestern France, which is now modern day Dordogne (1). This species existed during the Upper Paleolithic era and the site was carbon dated to 35,000-10,000 years ago (2). Five Cro-Magnon individuals were found, one infant, one female, and three males dated at 28,000 years ago (2). These…

Sinus infections caused by infection of pathogenic microorganisms (viruses, bacteria, or fungi), which grow inside the sinuses and cause intermittent obstruction of slot Pocket. Most people do not convey sinus infections. Most doctors agree that except in rare cases, sinus infections are not contagious but arising mainly viruses and bacteria that, by chance, someone pockets support deployment because Minor, rarely, and distortions in the sinus tissue of a person (for example, swelling,…

As a young girl, my neighborhood friend and I would stargaze consistently throughout the summer. We would lay on her trampoline, look at the stars, and have detailed conversations about space. While we were lying down in the palpable darkness, we would identify as many constellations as possible. Although, the main night that stands out to me, was when her father brought his telescope outside to give us a close viewing of Jupiter. That moment still affects me today since I have continued to…

X-Rays Development of the X-Ray In 1895, a mechanical engineer and physicist named Wilhelm Roentgen created the X-ray. He was born on March 27, 1845 in Germany. So in 1895, Roentgen was playing around with a cathode ray tube and evacuated all the air inside of it and replaced it with another special gas. Then, he covered the tube so nothing escapes it, passed a current through it, and then the tube produced a fluorescent glow. After further investigations, Roentgen wanted to see how strong this…

said in a language. Especially the English language. While Precession may have been looked at as angles of torque for physics or body mechanics; in astronomy precession refers to any of several slow changes in an astronomical body's rotational or orbital parameters. An example would be the steady change in the orientation of the axis of rotation of the Earth. How the earth rotates and what angle it is at changes many things. The sky we see today is different than the sky the people thousands of…

"The Battle Above." CBS News David Martin corresponded the CBS "60 Minutes" documentary "The Battle Above", depicting China's threats on our satellites within all orbital regimes that are critical to national security and everyday life. He clearly articulates that space is not a peaceful haven. Martin shares how our nation depend on satellites in space, and not just our civilian sector, but our military as well. "Satellites are used to communicate with troops, gather intelligence, fly drones and…

GPS WORKS Earth is surrounded by navigation satellites. Over 30 navigation satellites are zipping around high on the top of the Earth. GPS satellites encircle the Earth two times a day in a precise path. Every satellite sends a unique signal and orbital specifications that allow GPS devices to interpret and figure out the actual position of the satellite.…

moons. They are all very small but one is thought to be bigger than Pluto, its name is Charon. The other four names are Hydra, Nix, Kerberos, and Styx. Pluto’s orbit: It takes 248 Earth years for Pluto to complete one orbit around the Sun. Its orbital path doesn't lie in the same plane as the eight planets, but is positioned at an angle of 17°. Its orbit is also more oval shaped, or…
