New prime Herald's perfect discovery

Six is an interesting number. If you add its factors 1, 2 and 3 together, you get 6. This is a neat trick that only works for some numbers, and mathematicians describe these numbers as perfect.

discoveryThe next perfect number after 6 is 28 (1 + 2 + 4 + 7 + 14 = 28), and the third perfect number is 496. But most numbers aren’t perfect. Numbers with a sum of factors that falls short of the number are known as deficient. An example is 14, where 1 + 2 + 7 = 10. Others, such as 24, have too large a sum, (1 + 2 + 3 + 4 + 6 + 8 + 12 = 36) and are called abundant.

We have found some interesting clues to help us search for perfect numbers. The Greek geometer Euclid found a way of constructing perfect even numbers. He took a type of special number called Mersenne primes and multiplied them by a certain number of 2s. Many years after Euclid, the renowned mathematician Euler showed that all perfect even numbers could be made using Euclid’s formula.

Monitoring Software

The Internet can be tricky for parents to deal with because kids often need to use the Internet for school, but parents parents are often worried about the various activities that their children might be engaged in. Peer-to-peer file sharing can lead to lawsuits and even a criminal prosecution. Some teens might engage in activities online that are embarrassing to the family or may lead to viruses or hackers accessing the computer. Fortunately, there are various forms of monitoring software that can offer parental control.

Monitoring software can also be very helpful when parents are trying to learn what their children are up to, such as whether they are attending class or doing their homework.

Many teens use the computer purchased specifically for schoolwork to play computer games or chat with friends. Monitoring software can not only record activities on the computer, but smartphone software such as Mobile Spy can silently record the teen's GPS information, text messages and phone call information.

Monitoring software sits silently on a computer or mobile device and monitors all of the activities carried out on the device, encouraging the teen to consistently use the device for communication. Activity is usually uploaded to an online account so that the parent can monitor activity from anywhere without having to get close to the phone. This is crucial since parents will usually not have physical access to the phone without arousing suspicion.

Many monitoring programs also come with keystroke loggers, which log keys recorded on the computer, a contextual blocker, and features that allow parents to block certain websites. All of these features allow parents to have a peace of mind when allowing their teens to use the Internet.
