I have been obsessed with measurement for a long time and I'm not sure quite how it happened. The world's roundest object played a role in this. I guess I'm just fascinated by how difficult it is to pin down a quantity like a kilogram. A physical object seemed like a good idea until the mass of the international prototype kilogram wasn't as constant as expected. These methods of the Kibble balance and silicon sphere have shown better precision than 20 parts per billion, making them superior to the old method. The agreement between Avogadro approaches

Synthetic Biology One

Hello Everyone,
I’ve created these videos primarily as instructional aides for new students, interns, and trainees in my research group. While many of the methods are generally applicable, I am of course producing these demonstrations with the materials, reagents, and equipment that are available in our lab. Also, I’ll occasionally reference the locations of items in our lab.
In this video, I go over how to measure the optical density of a bacterial cell culture using an Eppendorf Biophotometer. Determining the optical density at 600 nanometers (OD600) of a sample provides a simple means of monitoring the cell density of that culture. The machine is just measuring (Intensity of light in) – (Intensity of light out), but most biomolecules absorb relatively little light at 600nm so this is largely a measure of light scattering by suspended particulate matter. Your cells will comprise the vast majority of the suspended particulate matter, thus OD600 is an effective measurement of cell density.
Please note that the relationship between OD600 and absolute cell density (cells per unit volume) is heavily dependent upon (1) the size and shape of the cells and (2) the actual density and optical properties of the cells themselves. As a result, the same OD600 reading would mean different cell densities for different organisms.
Other considerations:
-- For the tapered “semi-micro” cuvettes like the ones I’m using, a sample volume of 0.8mL is sufficient to get a good measurement. Of course, this volume will depend on the make of the cuvettes that you are using.
-- When handling a cell cultures, try to work under a flame with good aseptic technique.
-- In order to make sure that the sample you aspirate is representative of the whole cell culture, make sure that the culture is well-mixed immediately before taking a sample and that you’re sampling from the middle (not the bottom or the top) of the culture.
-- A cuvette that has had a cell sample sitting in it for a while may have experienced some settling. Either re-suspend your sample by pipetting or take a new sample.
-- Bubbles throughout your sample volume may wildly alter your measurement. If there are bubbles stuck to the walls of the cuvette, try to get these up to the top by gently tapping the cuvette on the bench-top.
-- Unless you are trying to take a very precise measurement, it’s usually fine to blank with water (unless you’re using TB or a similarly dark growth medium). You can also blank with water and then subtract a “fudge factor” to account for your growth medium. The absorbance of the different growth media at 600nm should be fairly consistent.
About me: I am currently (at the time of uploading this video) a doctoral student in the Chemical and Biomolecular Engineering department at The Ohio State University. My advisor is Dr. David Wood, and our research group specializes in protein engineering and downstream processing for the biotechnology industry. I’m also very new at producing instructional videos so I apologize in advance if these are not of professional quality. For instance, in my first few videos I did not know how to get rid of the timestamp (which is wrong), however I posted them anyways.
Please keep comments civil and apolitical. You are of course welcome to ask questions, however it is unlikely that I will answer them if you are not a member of my research group.
Thanks for watching,
Steven

This tutorial shows you the easiest way to calculate an IV drip rate. Using this 3 step formula, if you use the correct units in each step, you will get the right answer every time. If you have any questions feel free to comment below.
Remember:
Flow rate = ml/hour (varies depending on question)
Drop factor = gtt/ml (varies depending on question)
Time conversion = 1 hour/60 minutes (always the same for this method)

We can weight everything even we can weight ourselves. This is an important Maths lesson because you will need this everywhere in your life when you go to a shop and purchase any material such as Sugar, rice etc. You need to ask them 1kg or 2kg of rice then they can give you that quantity and charge you accordingly. You should know the concept of weight so that you will not get cheated anywhere.
In this Video, Bob explains the basics of weight and explains how different objects have to be taken in different amounts to make up the same weight.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

A unit is the frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units. Hank thinks this is a thrilling subject, and while you may not agree, it is a subject that is very important if you want to be a scientist and communicate with accuracy and precision with other scientists. So listen up and learn something or Hank might have to kill you! (NOT REALLY!)

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

How to Calculate your Body Mass Index:
You need 3 easy steps:
a) Measure your weight (in pounds).
b) Measure your height (in inches).
c) Calculate BMI = 703 W / H^2
If your weight is in kilograms, and your height is in meters, use this formula instead:
BMI = W / H^2
Then, look at this table and find the meaning of your result
- less than 18.5 = thin
- from 18.6 to 24.9 = healthy
- from 24.5 to 29.9 = overweight
- more than 30 = obese
If in doubt, please look for professional advice.

The three factors that determine the type of work a motor can produce are speed, torque, and horsepower. Speed is defined as how fast the motor performs its work. For example, a shaft can rotate slowly or quickly. The typical units of measurement for rotational motor speed are Revolutions Per Minute, or rpm.
