How to Calculate Accuracy in Chemistry

How to Calculate Accuracy in ChemistryThere are many misconceptions and fallacies out there about the science of chemistry, so the question is how to calculate accuracy in chemistry. Chemistry is an immensely fascinating subject, and it is important to understand the science behind its complexities. It's only by applying the basic principles of chemistry that we can appreciate the countless benefits that the study of this field can bring.What exactly is accurate? If you have a piece of equipment, you would use it correctly, without error, every time. This isn't the same as saying that your equipment is perfect, but it does mean that it will work accurately on a consistent basis. So, to get the best out of your equipment, and for your purposes, the method of calibration is essential.Calibration is the act of testing and determining the accuracy of certain life functions and parameters. The basic principle of calibration is to discover the right level of accuracy to which an item is ex pected to respond. For example, in life sciences, calipers are used to determine the exact size of specimen.Calculating the precise quantity of acid in a solution is dependent on knowing the exact measure of measurement that you have decided upon. Calipers are ideal for this, since they are capable of measuring accurately in three dimensions. You'll be able to find a professional that can give you a more in-depth explanation about calibration, but essentially it involves an accurate and repeatable process for determining the accuracy of a test.A test will usually be calibrated on a number of different types of equipment. One of the most popular forms of calibration is using lab glassware. You may already have a limited knowledge of how your instrument works, but you can still calibrate it with laboratory glassware. You can use a lab apparatus to give you a more accurate reading.Calibration is a simple process. You'll need some test tubes or flasks, some small amounts of test compoun d, and some medium (in this case, some glucose). Then you put the correct amount of test compound in the test tube or flask and wait for the indicator to turn from red to green. This tells you that the test is currently properly calibrated.To become a good chemist, you will need to study and practice the concepts of calibration. As a practicing chemist, you'll need to be sure that you can accurately calibrate your tests for accuracy. Many times you will find that this is far more important than any other aspect of accuracy that you may consider.So remember, if you're seeking accurate results from your research, then calibrate your samples and instruments. By taking the time to properly calibrate your samples and instruments, you will be able to ensure that your efforts are all in good working order.

The History Of Vegetarianism

The History Of Vegetarianism Vegetarianism: A History ChaptersEarly Man: The Hunting InstinctBefore Christ: Religion And Vegetarianism1700-1800s: A More Romantic Take On The Feelings Of Animals1800-1900s: The Birth Of The Vegetarian Society1900-2000s: Modern Day VegetarianismWhile you might think that vegetarianism is quite a recent ideology, the fact is that people have been eating plant-based diets for as long as they have been eating animal products like meat, eggs and dairy products.Views on a vegetarian diet differed, and continue to differ, in different parts of the world and across the different faiths.Religion has played a very big part in both the undermining of animal species and in overturning the outlook that humans are superior to creatures.Keep reading to find out more about the history of the vegetarianism movement and who played a major role in driving it.the first to show independent thinking concerning animal cruelty, and argued that all species on the planet should have equal rights.But before him, ancient Egyptians a nd Babylonians had long-practised a vegetarian ideology as part of their religious beliefs, which meant that they abstained from eating and wearing any animal-derived products. This was rooted in their nature from as early as 3,200 BCE.But it was Pythagoras himself who took it upon himself to champion the health benefits of a vegetarian way of life and, as we know, he was not a stupid man. Though his scientific evidence was lacking, he viewed a life abstaining from animal products not only as a way to co-exist peacefully on Earth, but as a way to benefit the human: by giving them purity of the soul.Other famous Greek names opposed this view, including Socrates, Plato and Aristotle who all firmly believed that animals were put on Earth to be slaves, and therefore had no place other than to become meat for us to eat or clothes to wear. They had very limited sympathy for the butchering of them for meat, and thought Pythagoras' views weren't worthy of recognition.Back in the day, many h ad no sympathy for the animals being slaughtered, even if it was in a barbaric way. Photo credit: Farm Sanctuary on Visual HuntWhile kindness to animals has long been a part of Eastern religious beliefs, for instance in Ancient Egyptian mythology where some  animals were seen as sacred gods,  Christianity saw humans as the superior living species and thus anyone who disagreed with this notion was seen as deviants or fanatics and were even persecuted for voicing their opinions.

Leonardo Da Vinci, the famous painter and inventor, was repulsed by the thought of animal slaughter, as were many classical writers of the time. They touchingly put into words the powerful notion that animals could indeed feel and think, just like humans.John Clare, for instance, wrote about a badger that was captured and baited in his poem titled Badger, meanwhile Ted Hughes remarks on the fate of pigs in a slaughterhouse in his poem View of a Pig. Da Vinci often used wild animals as the subjects of his studies and drawings.With the Enlightenment period of the 18th centu ry came more opposing views on the place of humans and animals in the order of creation, with some arguing that animals were soulless robots and others debating that they were intelligent creatures that could feel and communicate. At this time, slaughter methods were truly horrific.1800-1900s: The Birth Of The Vegetarian SocietyIn the 19th century, romance prevailed and in 1809, a noteworthy move towards vegetarianism as part of Christian faith was established. From this day on, many began to appeal against meat eating, using biblical references to back up their theories.In 1847, in the UK,  The Vegetarian Society was formed and by the 1880s, vegetarian restaurants had began to pop up across the capital making nutritional, vegetarian meals easier to come by. This meant that followers of the cause could celebrate the vegetable with other like-minded individuals within their community.Finally, with British health still severely inadequate, The Vegetarian Society would send food to dep rived communities in an act of humanitarianism to help save the people.The food shortages in the meat industry that resulted from WWII meant that people were encouraged to dig to source food, and many therefore lived on a near-vegetarian diet throughout the war. In 1945, approximately 100,000 Britons were vegetarian.Food parcels during the war would have included bare essentials to keep people alive. Photo credit: HereIsTom on Visual Hunt1900-2000s: Modern Day VegetarianismToday, the society believes that the number of committed vegetarians has risen to almost 2million, and thanks the shops and supermarkets that stock frozen vegetarian goods like quorn mince and tofu pieces for this growth. Without them making ingredients for vegetarian dinner recipes so accessible, this number may be much lower.It was during the 1950s and 1960s that people started to become much more aware of their health and made links between how they could control their wellbeing by adapting their diet and other life choices. That said, cigarettes and other tobacco products were high in demand so scientists and health experts still had a long way to go in assessing what was good for the human body.Meanwhile, the 1980s and 1990s revealed the true devastation that humanity was having on the Earth, and so vegetarianism rose once again. More people began to take notice of other options available to them than animal protein and began shifting towards a meatless diet.Vegetarians today are campaigning for a change in the way that animals are treated, with animal experimentation and factory farming having already been brought to light. Not to mention the fact that they are striving to convince others of the benefits of going vegetarian, like the campaign National Vegetarian Week which takes place in May this year. The same can be said of the vegan community. Vegans abstain from all products that derive from animals. As well as avoiding meat, vegans do not consume eggs, dairy or use products that h ave been created at the cost of animal suffering.Anyone can join, even if they don't plan to continue with a meat-free diet afterwards. The idea is to highlight the health benefits of vegetarianism by encouraging people to try it out, in the hope that they will want to stick it out for longer and potentially become a permanent veggie.If this interests you, or you want to invite a friend to join you eating meat-free food for the week, then you can sign up for the campaign's newsletters which will be packed full of fantastic vegetarian recipes, helpful information and competitions throughout the course of the week.If, however, you don't think you can eat vegetarian dishes for an entire week, then why not try Meatless Monday, which is a gentler way to introduce a meat eater to meatless meals.Some of the recipes you could try are: stir fried noodles with tofu in a peanut sauce, macaroni and cheese with a spinach salad on the side, portobello mushroom wellington with roasted cauliflower and sprouts, goat cheese and caramelized onion quiche with Mediterranean roasted vegetables, Mexican bean chili with tortilla crisps and an avocado salad, sweet potato frittata with kale and asparagus, cheesy cannelloni with a tomato salad, onion tart with carrot salad, curried potato curry with pickled chutney, grilled bean burger with a sweetcorn and carrot salad topped with a balsamic vinaigrette, pumpkin soup with bread to dip in, feta stuffed pepper with spiced couscous, black bean burritos with wild rice, mushroom and parmesan arancini (risotto balls) coated in fried garlicky bread crumbs... Or, if you prefer fast and easy recipes, then you could try things like avocado on toast, hummus with sliced peppers and pitta bread, tomato, onion and pesto bruschetta, vegetarian lasagna, or simple pasta recipes. You see, your healthy dinner doesn't have to be boring!You can find many more free recipes online, including vegetarian breakfast recipes, side dishes, puddings and, of course, more vegetarian  dinner recipes.Remember that seeds and nuts like pecan, cashews or pine nuts, for example, are great for adding texture. Also, if you really want to embrace a healthy lifestyle, then stop munching on biscuits for your mid-morning snack and instead crunch on some pumpkin seeds!That said, even vegetarians like to 'veg' out on the sofa with a tasty treat. So you can still enjoy a bowl of mozzarella and salsa topped nachos with friends - it is allowed!If you fancy trying your hand at creating your own fragrant and mouth watering meat-free dishes but are stuck for ideas to base your meal around, then you might be interested to know about these delicious yet less mainstream products that are great to cook with: quinoa, lentils, polenta, arugula, acorn squash, seitan, artichoke, orzo, gnudi, tempeh, farro salad, bok choy, yukon gold potatoes, okra and cremini mushrooms.While you might not find all of them in your local supermarket, you're sure to be able to source them fro m specialist shops that cater for vegans and vegetarians.Further Reading And LinksIf you found this article an interesting read, then why not read others on vegetarian cooking, such as:Tips To Be A Healthy VegetarianThe Best UK Vegetarian Food BloggersFind cooking classes
