What is the first reaction of medical students seeing a cadaver for the first time in their lives?
I was not yet in med school when I saw a cadaver for the first time; I was a pre-med sophomore in college (just last semester).Ever since I decided I wanted to go into the medical field, I have wanted to see a cadaver. As a thirteen year old, I would spend hours watching human dissection videos on YouTube, but I knew nothing would compare to the real thing when the time finally came.The day I got to see a cadaver in Anatomy class, I couldn't keep my eyes off them. I had wondered if I would feel scared when this moment came, but I felt no fear as I approached the cadaver, only curiosity.The cadavers had no skin on their bodies (only on their nose, lips, ears, eyelids, etc), so all of the students in the room could see every muscle as they stretched over bones.As I stared at them, I tried to imagine what they would have been like when they were alive.Had they lived in the area? Was it possible that I had once crossed paths with this person? Did they have a family out there? Someone who had cared for them? Did they have children? Grandchilren? Did they like to go the gym? Had they also enjoyed the tv shows that I like? What was their favorite food? What had their last moments been like? What had made them decide to donate their bodies to science? How did their loved ones feel about that choice?As I processed all of this, there was also a part of me that could not ignore the smell in that room. It was, at the time, one of the worst things I had ever smelled. My professor had told us the week before to make sure that we had had breakfast before coming into class in order to prevent feeling overwhelmed by the smell of the formaldehyde. Luckily, I had listened to him. Otherwise, I would have had to leave the room in search for fresh air. After another class though, the smell did not bother me anymore.As I all of this was running through my mind, I could not help but be amazed by the experience (I hope that this does not come off as morbid). The muscles were just perfect. The lungs were incredible and the heart was beautiful.All in all, the first time seeing a cadaver was exhilarating.Lifting up the front of a ribcage and seeing the heart sitting there can never compare to seeing pictures in our textbooks.———To the people who have donated their body to science and to the people who are planning on doing it, we cannot thank you enough.
How did the German soldier react to their first encounter with tanks in WW1?
History rarely records the thoughts of those on the receiving end of a new ‘wonder weapon’ in battle – such as the first sailors doused with Greek Fire over 1,300 years ago, or those soldiers facing the first crossbow bolts over 2,500 years ago, or showered with arrows from the first fast-moving chariots 4,000 years ago. Unquestionably there would have been panic and confusion when it became clear that a distinctly new weapon, never before experienced, was being used against them. Here are the first of two rare sets of accounts of witnesses to the moment when something about to change warfare forever suddenly and unexpectedly hoves into view…The morning of 15 September 1916 dawned foggy near the village of Flers in northwestern France. German soldiers of the 28th Reserve Infantry Regiment crawled wearily out of their buried dugouts and huddled in their trenches, expecting the Allied assault that usually followed an artillery bombardment of the intensity they had just endured.The brief lull between the end of the bombardment and the crescendo of the creeping barrage which paved the way for the Allied advance was broken by the strange roar of engines. As the Germans took up their defensive positions and looked out over no-man’s land towards the British lines, a number of objects appeared in the distance that at first were difficult to discern.A German war correspondent described his first impressions:“My blood froze in my veins. Crawling along the cratered battlefield were two mysterious monsters. The monsters approached slowly – limping, staggering, swaying – but no obstacle could stop them. They moved ever forward with a supernatural force. Our machine-gun fire and hand grenades simply bounced off them. They were thus able to easily destroy our crews in the forward shell-holes, then run straight through the German front line and off into the village of Flers, where they stayed for some time. The British infantry which had followed them took possession of the village, and the machines drove off down the Ligny-Tilloy road.”
Define the following symbols that are encountered in rate equations in chemistry?
The first is initial concentration of the species in the integrated rate laws before reaction occurs (pronounced A "nocht" or however its spelled). Could be less or more than the final amount. b. this is the time for a half life, or the time for one half of the species to disappear. Each subsquent half life, one half of each amount remaining disappears. c. Rate = k[species][species] (rate law) k = rate/[species][species] k units depend on rate/ how many species there are and how these units cancel, but k is the rate constant and usually equals k-1 for a first order reaction Finally, the natural logarithm of the concentration of the species (molecule, molecules, atom, referring to anything) on the y-axis versus time (usually seconds) on the x-axis yields a straight line.
Should I count this as my first sexual encounter?
Sex comes in all different forms. This was a sexual encounter, though not intercourse. You don't say how old you are. But throughout your teen years and beyond, your hormones will be working overtime. Be sure you are ready to take responsibility for your actions before you go too far. And when I say "take responsibility" I mean think very far ahead so you don't make any mistakes you'll regret later on.
A motorist traveling at 16 m/s encounters a deer in the road?
Let's first find the stopping distance once deceleration begins. This can be found using one of the kinematic equations of motion. We have the following information: u = initial velocity = 16 m/s a = acceleration = -5 m/s² v = final velocity = 0 m/s d = stopping distance = ? v² = u² + 2ad. Since v = 0, we must have 2ad = -u², and therefore d = -u²/2d = (16 m/s)²/2(5 m/s²) = 25.6 m. So it takes her 25.6 m once she starts braking. Her maximum possible reaction time must be the time it takes for her to travel 41 m - 25.6 m = 15.4 m. As that's before she begins braking, her velocity would be constant over that period, and therefore the reaction time is just distance divided by speed = (15.4 m)/(16 m/s) = 0.9625 s. B: During that time she will travel a distance of (1.1925 s)(16 m/s) = 19.08 m, meaning she decelerates for 41 m - 19.08 m = 21.92 m before hitting the deer. Here we use v² = u² + 2ad again but this time v is our unknown that we're finding instead of d. v² = (16 m/s)² + 2(-5 m/s²)(21.92 m) = 256 - 219.2 = 36.8 and taking the square root gives a speed of 6.1 m/s²
How would dinosaurs have reacted if they see humans for the first time?
dinosaurs would probably react similarly to how other animals react to us. dinosaurs do interact, and have interacted with humans, trust me, that whole taken out by an asteroid thing is nothing more than nonsense. dragon legends from all other the world, could not have imagined the same thin in their minds, they must've encountered dinosaurs, or what was left of them. back then, most people would hunt them down, mostly carnivorous ones, since they are the real threat to any human civilization. big dinosaurs like T-rex, spinosaurus and allosaurus would've been dealt with quickly, either for safety concerns, or for money and fame. larger herbivores would be taken out too, most of them have worrisome features, like armor, spikes, horns, claws that seem threatening in nature. concerning the rest, probably flee to jungles, and a handful of dinosaurs could very well disappear in vast jungles of south America, or Africa, and sea dwelling dinosaurs might just be elusive to man's reach. if a modern man were to encounter a dinosaur for the first time, depends on the dinosaur they encounter. even though any dinosaur would shock them, a known carnivorous dinosaur would make them run for the hills. a dinosaur might be unphased by the presense of a human, because not many encounters have been recorded ( unlike Mokele Mbembe a supposed sauropod dinosaur) any dinosaur might be curious as to what we might be, possibly not be afraid of us whatsoever, but might get territorial, we do not entirely know dinosaurs mentally, so there's no telling how they might respond
