https://www.youtube.com/embed/bHglySrR5vs What are pilots? My name is Mahir Cave We will show you how to make a paper plane. Today’s paper plane looks great and it’s easy to do – so let’s put it together! But first – look at how it flies. Take a sheet of paper. Set the video quality to a higher resolution and let’s get started. If you’re new to my channel – don’t forget read the tips in the description. And also sign up I record a video like this every Thursday. Keep in mind that both sides should look the same. Turn the paper over. Slowly hold your hips smoothly. Turn the paper over. Turn the paper over. Now lower it and check that it remains on the center line. Fold this line – on this. Mark this point. Hold it as you lower this corner – to this row. Turn the paper over…

https://www.youtube.com/embed/Tp2M9tndGG0 Frostbite Theater presents… Cold Cuts! No baloney! Just science! Hi! I’m Joanna! And I’m Steve! We’re finally ready to calculate the half-life of metastable barium-137 using the data that you collected earlier. If you haven’t collected any data, you may want to watch the first two videos in this series. We’re going to start with an equation. Don’t panic. As far as equations go in physics, this one isn’t too bad. This equation tells us that the activity of a radioactive substance at any time ‘t’ is equal to some initial activity multiplied by ‘e’ raised to the power of negative lambda ‘t,’ where lambda is the decay constant of the particular radioactive isotope and ‘t’ is the time. Our first goal is to find lambda, the decay constant. In order to do that, we need to know how the activity of the sample changed over time. Now, the…

The goal of the treatment is to reshape the cornea to correct the refractive error of the eye. The cornea is the transparent dome-shaped structure in front of the eye. The cornea refracts light and accounts for about two-thirds of the eye’s total optical power. Altering the curvature of the cornea changes the way light rays enter the eye.As a result, the light rays can be focused properly onto the retina for clearer vision. For nearsighted people, the laser is used to flatten the cornea. For farsighted people, the cornea is made steeper. For patients with astigmatism, the laser is used to smooth the irregularly-shaped cornea into a more regular shape. The outer layer of the cornea – the epithelium – is capable of replacing itself within a few…

https://www.youtube.com/embed/XfyGv-xwjlI Diabetes refers to a group of conditions characterized by a high level of blood glucose, commonly referred to as blood sugar. Too much sugar in the blood can cause serious, sometimes life-threatening health problems. There are two types of chronic diabetic conditions: type 1 diabetes and type 2 diabetes. Pregnant women may acquire a transient form of the disease called “gestational diabetes” which usually resolves after the birth of baby. Pre-diabetes is when the blood sugar level is at the borderline: higher than normal, but lower than in diabetics.Prediabetes may or may not progress to diabetes. During food digestion, carbohydrates – or carb – break down into glucose which is carried by the bloodstream to various organs of the body. Insulin is a hormone produced by beta cells of the pancreas and is necessary for glucose intake by target cells. In healthy people, beta cells of the pancreas produce…
