There is a truism in aviation that flying requires safety and there is nothing funny about safety. While stern in appearance, this is not the same as saying there is no fun in flying. If there weren’t, why would we pursue flying in the first place? Ask any pilot and you get stories of flying adventures, feelings of freedom in the air, and pure “joie de vivre” through flight. Safety, and the procedures required for it, are part of the aviation process.
Scientists use the term dark matter” to describe something they have evidence for but cant see hence the dark.” They think its dispersed throughout the universe. Dont look now, but its around you, too.
Dark matter isnt evenly spread. Its bunched up in some regions and drawn out in others. Its job is simple: holding the universe together .
This cosmological adhesive is likely an entirely new type of matter that isnt close to being understood.
The field of medicine is a very noble profession and is also rewarding both financially and emotionally. Today, the demand for medical professionals has increased greatly due to the changes in lifestyle and the increased population of the world. Though medical professional salaries depend upon many factors, they are still very high compared to other fields.
Pharmacy technicians typically support and assist a licensed pharmacist in a hospital or other medical facility. The main job of pharmacy technicians is to interact with patients, make the prescribed medicines available and perform other administrative tasks.
Naming aromatic compounds is a topic you will likely come across somewhere in the middle of your organic chemistry course. This may come up during the topic of aromaticity and conjugation, or perhaps during EAS – Electrophilic Aromatic Substitution. In this article I will give you a quick overview of the ortho, meta, and para naming system to help you recognize these compounds and apply them to your reactions
Since benzene is a conjugated 6-member ring, it is much easier to use a designation system for identifying the relationship of substituents on a molecule compared to the standard numbering.
If you have just 2 substituents on your aromatic ring you can use the prefixes ortho, meta, or para to identify the relationship of the 2 groups around the ring
Ortho substituents are located just 1 carbon away from the primary functional group.
For regions that experience snow, ice and freezing rains during the winter months, de-icing salts are a common method of keeping roads safe. However, numerous studies throughout the years have shown road salts to be hazardous to the environment. The chemical make-up of salts used for de-icing purposes can include sodium chloride, calcium chloride, potassium chloride and magnesium chloride.
The Newman Projection is an important skill for every organic chemistry student. Not only does it provide you with another perspective of organic compounds, but it also gives you a means to analyze the conformational energy of a molecule. In this article I will give you a quick introduction to the energy diagram of a Newman Projection.
Unlike a sawhorse projection in which a molecule is read left to right or right to left, in a Newman Projection the molecule is angled so that you wind up looking right down the bond between 2 carbon atoms.
If you like to cook you probably go into your kitchen with the idea that you are going to produce a very delicious meal that everyone will like. But did you realise that every time you enter the kitchen you are doing applied science?
Science is full of theories and formulas. Did you know that you use lots of theories and formulas in the kitchen? Did you know that every recipe is a formula? Let’s take a look at science in your kitchen:
The First Law of Thermodynamics – Every time you strike a match to light your gas stove, you are putting into play the First Law of Thermodynamics.
Centrifuges are among the most demanded laboratory equipment and are used for various applications in medical and scientific laboratories. Regardless of the use, it is essential to purchase branded equipment to ensure reliability and durability. Leading manufacturers offer both floor and bench top models. The best way to purchase the equipment is to examine your requirements and choose a premium quality device based on this.
I think everyone would agree that before they were thought of in anyone’s philosophy, the Universe existed. You’d agree that the Universe existed before humans existed, unless you’re one of those fundamentalists who interpret the Book of Genesis literally, and even then there were a few days for the Universe to enjoy a pre-human existence. If you’re not one of those extreme right wing all-things-literal Christians, then you’d go along with the Universe existing before life, any kind of life, arose on Terra Firma (or anywhere else in the cosmos for that matter).
Organic chemistry is not your average science course. And so your approach to learning and mastering this information must also be above average. While organic chemistry scores tend to be lower than any other science, by reading this article you will learn how to get an above average grade in organic chemistry by working with a study group.
Organic chemistry is a course that can only be mastered by gaining a deep understanding of concepts and developing a proper approach to working through reactions and mechanisms.
Setting up a consistent study schedule should be your primary goal, however it may not be enough.
When you study alone you are limited to the information that you are able to master by yourself.
