How To: Understand organic molecules in chemistry

In this video, we learn how to understand organic molecules in Chemistry. First, you will need to take a look at the chemicals that are inside of each of the different molecules. See how the molecules are made out and then see what number of different acids are inside of them. Once you learn this, you can see what the difference between this and other molecules are. This can all help you understand the beginning and end of what's inside of the molecules. If you aren't good at chemistry, you w...

How To: Understand diffusion & osmosis

Inside the container we have some water molecules and inside those water molecules we have some sugar molecules. We have more water molecules so in this case the thing which is more of called SOLVENT and the thing which is lesser is called SOLUTE. We can say sugar molecule dissolves in the water. The combination of Solvent and Solute is called the SOLUTION. Diffusion is spreading the molecules from high concentration to low concentration. If we take two containers of water which are joined fr...

How To: Describe chemical formulas

This is a video tutorial in the Education category where you are going to learn how to describe chemical formulas. A chemical formula represents the actual number of atoms of each element within a molecule. Different visual representations of molecules include the ball and stick three dimensional model, a line drawing that represents the structure in two dimensional terms, and a shorthand used by organic chemists. If a molecule has 4 green atoms and 2 orange atoms, the ratio of green to orang...

How To: Remove date and time stamps from your photos

There are various ways to remove the timestamp on your photos using Photoshop. You can use the crop too and crop out the photo, but then you'll lose parts of the photo as well. You can use the patch tool, and draw a border around the date, then drag the date to another area, let go and press ctrl+D. The time will disappear and the area will be patched up with surrounding colors. Another method is to use the spot helium brush tool, and simply just brush over the text, and the spot helium brush...

How To: Completely Back Up Your Apps & App Data on Your HTC One or Other Android Device

When you upgrade to a new Android smartphone like the HTC One, you can have browser bookmarks, Wi-Fi passwords, and other settings quickly transferred over from your old device using your Google Account backup. However, you'll still have to download apps individually from your Google Play list, and not all of your saved progress will be transferred over. Fortunately, there is a third-party app that will allow you to backup and restore your apps—with all their data.

How To: Understand the hemoglobin & its role in the body

An in-depth explanation of the structure of the hemoglobin molecule, the process by which it binds with the oxygen in the lungs, how it dumps the same oxygen molecule at the appropriate location in the body and how carbon-dioxide gets attached to the hemoglobin molecule are the topics which the narrator in this video explains with diagrams and a few equations.

How To: Understand resonant frequencies

In this video tutorial the instructor demonstrates resonant frequency. In this video the instructor shows the sound of resonance and how to generate it. Resonance is a forced vibration of energy into molecules of an object that makes those molecules vibrate at their resonant frequency. When these molecules vibrate naturally they produce a kind of noise that can be annoying some times. In this video the author makes a small object using a rubber band and a net that produces vibrations when rot...

How To: Back Up Your Nexus 7 Without Rooting or Adding a Custom Recovery

At some point, we all need to back up our device. Maybe it's time to take it in for repairs or maybe you're just cautious and paranoid. Maybe you're trying out a new ROM on your Nexus 7—then you definitely need to back up. The most secure way would be to use a custom recovery like ClockworkMod or TWRP, but if you're not rooted or planning to root, then you'll need an easy alternative.

How To: Understand organic molecules & elimination reaction

This video helps us understand the organic molecules and elimination reaction. Take some sugar in a beaker. Sugar has 12 carbon atoms, 22 hydrogen atoms and 11 atoms of oxygen. The sulphuric acid is poured into the sugar and the color change is observed. The color of the sugar gradually changes into black. The sulphuric acid causes an exothermic reaction which releases a large amount of sulphur dioxide gas. All the water (containing hydrogen and oxygen atoms) is eliminated out of the sugar du...

How To: Understand organic molecules & oxidation in Chemistry

Do you understand organic molecules or oxidization in chemistry? If you answered no then this is the video you need to watch. This video will show you grade 12 chemistry, with organic models, and will teach you about oxidization. In less than 4 minutes you will have a much better understanding of the topic. This is demonstrated with a few common chemicals which include potassium dichromate and ascorbic acid. Ascorbic acid or vitamin C is found in many foods that we eat including fruits and ve...

How To: Photograph from the sky with a homemade balloon

In this video, you will find some tips on making an aerial camera to take footage from the sky. To make your own aerial camera, you will need to follow these steps: Buy some metalized nylon from balloon kits.com. Use a hot iron to see the nylon pieces together. Check for any air leaks by using a shop vac's exhaust. Patch any holes with extra nylon or duct tape. Fill the balloon with helium. Attach a box to the balloon with some mesh tape. This box will hold your camera. Allow friends to hold ...

How To: Easily balance a chemical equation

In this video, we learn how to easily balance a chemical equation. In a balanced equation, there should be the same number of atoms on both sides of it. There are no rules that explain how you get a balanced reaction from expression. First, start on the molecule or compound that is the most atomically complex. After you look at this, you can learn how to make the rest of the equation equal to each side. This is a complex process that you must walk through to figure out, but it will result in ...

News: Sentinel Nerve Cells Spy on the Intestines, Linking Gut & Brain

If the all the fingerlike projections in our gut were flattened out, its surface area would be 100 times bigger than our skin's. It's so large that the actions of just a small part of it can impact our health. A new research study has found that enterochromaffin cells in the intestinal lining alert the nervous system to signs of trouble in the gut — trouble that ranges from bacterial products to inflammatory food molecules.
