The evolution of the scientific calculator The scientific calculator Although we may have begun using fingers and toes to count, mankind has been creating machines that aid in calculations for many centuries. From the earliest counting devices to the modern calculators many things have been created in the space between. Nowadays, professionals and students alike have access to technological calculators capable of performing complex mathematical functions as well as solving complex equations. They can save a lot of time when compared to writing out individual questions and equations. How did the inventors make the leap from the earliest abacus hundreds of years ago to the current scientific calculator? What is a scientific calculator? Scientific calculators , sometimes referred to as digital calculators , are electronic devices that are able to solve a variety of calculations that are used in math, engineering and science. Basic calculators generally h...

Random number generation Random number generation is a process in which, generally by means of an random number generator (RNG) an array of symbols or numbers that are not able to be predictable better than random chance is created. This means that the resultant sequence could contain patterns that can be seen in hindsight, but impossible to see in the future. In reality, random number generators can be hardware random-number generators (HRNGS) that generate random numbers, and each generation is determined by the value that is currently in a physical environment's attribute , which is constantly changing in a manner that's difficult to predict. This would be in contrast to so-called " random number generations" done by pseudorandom number generators (PRNGs) that generate numbers that only look random but are in fact pre-determined--these generations can be reproduced simply by knowing the state of the PRNG. Numerous applications of randomness have le...

Food restriction with time Does it work? A new study investigates whether eating a restricted diet can have positive health benefits. AleksandarNakic/Getty Images The outcomes of animal studies have shown significant metabolic benefits derived from restricting feeding. Initial human studies suggest that these findings may be beneficial to humans. A new study has looked at the evidence that has been gathered from both human and animal studies. The authors recommend more study is needed to find out the ways in how restricted eating habits can be beneficial and practical for humans. Researchers have looked at the evidence to support that eating a time-restricted diet -it is a kind of intermittent fasting where individuals eat only during the same time each day. The review, which is published in the journal of the Endocrine Society, Endocrine Reviews , researchers examined animal studies , as well the first human research...

Calculate your BMI Use the BMI calculator to get a snapshot of how healthy your weight is relative to your height. Body Mass Index ( BMI ) assesses your weight relative to your height and can be an excellent indicator of whether your weight falls within the, below or within a healthy range.

Exact Age Calculator It is an internet-based age calculator that allows you to easily calculate the exact age. The person's age is measured differently across different societies. This calculator is built on the most popular age system. With this age calculator it is all you need to select the date of your birthday and after you have to leave everything on the calculator. The result provided in this age calculator is fully accurate. In this model, age increases at birth. For instance that the age of someone who lives for three years or 11 months is 3 years , and his age will be 4 years old when he celebrates the next birthday after a month. In certain situations the numbers of months and dates calculated by the age calculator google could be misleading, particularly when the date of the start is the day that a month ends. For instance that we all count February. Exact Age Calculator It is an internet-based age calculator which allows you to easily calcu...

Random Number Generator Utilize this generator to obtain an absolutely random and cryptographically safe number. It generates random numbers that can be used where unbiased results are critical, such as playing shuffled decks of cards in a game of poker or drawing numbers for giveaways, lottery or sweepstake. How to pick what is a random number from two numbers? You can utilize this random number generator to generate an authentic random number among any two numbers. For instance, to generate an random number in the range of one to 10 (including 10, input 1 to the top box and 10 in the secondfield, after which press "Get Random Number". Our randomizer will pick a number from 1 through 10, all at random. For generating the random number between 1 and 100, repeat the process as above, except that you put 100 for the other field within the randomizer. To simulate a dice roll the range should be from 1 to 6 for a standard six-sided dice. If you want to gen...
