It has several unifying themes that link it all together. Evolution is also a major theme, which explains the unity of life. Also, it shows that organisms are capable of reproducing and controlling their environment. Biology has multiple subdisciplines, each of which is defined by the nature of the questions that they answer and the tools they use. Earth's diversity is astonishing. There are more than 400 known species of organisms living on Earth, and some of them are prokaryotic and eukaryotic. Word biology comes from the Ancient Greek words for the terms life and biologa.

Chemistry calculators

From this page you can find links to all kinds of calculators that relate to chemistry. Chemistry is the study of the properties of matter. It investigates the various elements that make up the universe. Chemistry is a basic scientific discipline that explains various aspects of life. It can also be used to explain concepts such as the formation of ozone, the effects of atmospheric pollutants, and the effects of certain medications. Chemistry talks about the interactions between atoms and molecules through chemical bonds. There are two kinds of chemical bonds: primary and secondary. They are known as ionic bonds and primary chemical bonds. The term chemistry comes from a modified word that refers to an earlier practice that included elements of chemistry, philosophy, medicine, and astronomy.

Calculators for construction and building

Check out these nice construction calculators! They help you when you want to build a cabin, renovate home, or do anything else! Construction is a general term that refers to the process of forming objects and systems. It comes from Latin constructio and Old French construction. Construction is the process of building or modifying an asset. It typically involves planning, designing, and financing the work. This step typically continues until the asset is ready for use. As of 2017, the construction industry is the largest employer in the world, with a workforce of approximately 273m people. It accounts for more than 10% of the global economy's total output. The first huts and shelters were made from simple tools and were often constructed by hand. During the Bronze Age, various professions such as carpenters and bricklayers emerged.

Financial calculators

Finances are usually heavily connected to money. We provide many financial calculators to help you on your daily finances. The history of money shows that various social and economic systems have at least one function related to money. Money can be in a physical form as coins and notes, or it can be electronic.

Some of these were also exchanged for more attractive items such as beads and cowrie shells.

Food and nutrition calculators

Healthy nutrition is crucial for healthy life. Food is a substance that's consumed by an organism to provide nutrients. It's usually a plant, animal, or fungal origin. The nutrients found in food keep the organism nourished and helps maintain growth. Different animals have feeding behaviours that are adapted to meet the needs of their unique metabolic systems. Humans have been using various farming techniques and hunting and gathering food for thousands of years. Through these methods, they were able to secure food for their families. The cuisines and cooking techniques developed by humans have evolved as they moved into agriculture. As cultures have become more integrated into the global food system, their traditions and practices have become more widely available. This has led to a flourishing exchange of food traditions and practices. Calculating different factors for food is easy with our food calculators!

Health and welfare calculators

Preventative healthcare is important for staying healthy. With the help of our calculators, prevention of many issues is easier than before. Prevention of disease is the process of taking preventive measures to prevent the development of diseases. Disease prevention can be divided into four broad categories: primary, secondary, tertiary, and primal. A study conducted by the American Heart Association revealed that about 400,000 people die in the US each year due to lifestyle factors such as obesity and poor diet. In 2000, 60% of deaths globally were attributed to chronic diseases. This is an increase from the previous year, which saw 60% of deaths attributed to these diseases.

Mathematical calculators

Need help in math? Our calculators let you excel in math. Mathematics is the study of various topics related to numbers, structure, and change. When mathematical structures are used to model real phenomena, they can provide predictions about nature. Practical math has been a human activity for many years. The research required to solve some of the most challenging problems can take years of inquiry. Since the work of Giuseppe Peano, David Hilbert, and others in the 19th century, it has been widely believed that scientific research is conducted by carefully analyzing and criticizing the correctness of selected axioms and definitions. The evolution of mathematics began during the Renaissance, when scientists began to develop new ideas and methods. It is widely used in various scientific fields. The emergence of applied mathematics has led to new disciplines such as game theory and statistics. The history of mathematics shows that the first major abstract was probably numbers. It was the realization that a lot of numbers have something in common.

Physics calculators

Our calculators will make your physics homework a piece of cake! Physics is a natural science that studies the behavior of matter. It focuses on the interactions between energy and force. Physics is among the oldest academic disciplines. Through its inclusion in astronomy, it is also considered to be the oldest branch of scientific research. Physics is often intermixed with other interdisciplinary fields of research, such as biophysicists and quantum chemists. Its boundary is not rigidly defined.

Computer calculators

A computer is a device that can be programmed to perform specific tasks, such as arithmetic and logical operations. The Internet is powered by computers, which connect millions of users. Early computers were designed to be used only for calculations. Many times computer related problems are annoying to solve. That is why we created nice collection of computer related calculators!

Fashion and beauty calculators

With the help of our calculators you can for example find your clothing size! Fashion is an expression of individuality and autonomy in a specific context.
