Recent Java enhancements for numeric calculations

Submitted by schekanov on Sat, 11/07/2020 - 11:46

In the past, slow evaluation of mathematical functions and large memory footprint were the most significant drawbacks of Java compared to C++/C for numeric computations and scientific data analysis. However, recent enhancements in the Java Virtual Machine (JVM) enabled faster and better numerical computing due to several enhancements in evaluating trigonometric functions.

Restored Wikipedia articles

Submitted by jworkorg on Thu, 08/20/2020 - 12:51

About 15,200 scholarly articles permanently removed from Wikipedia in 2018 and 2019 have been restored by the Handwiki team. In 2018 and 2019, such articles  did not pass the Wikipedia's notability. As the result of this, a lot of useful content  was lost. Articles on software programs and computing were the most affected by this Wikipedia trimming.

Currently the restored Wikipedia articles on computing, science and education can be found in HandWiki (https://handwiki.org). These articles cover the following topics:

JavaView (http://www.javaview.de/) is a 3D geometry viewer and a mathematical visualization software known since 90x. The program is written in Java, and enables a smooth integration into commercial software like Mathematica and Maple. JavaView can be used for 3D scientific visualization, geometric modeling, variational optimization, vector fields etc.

Can a human brain hold your life experience?

Submitted by jworkorg on Thu, 05/21/2020 - 14:36

A human brain is an amazing instrument. It combines huge data storage with massive real-time processing. According to Scientific American [1], the memory capacity of the human brain was reported to have the equivalent of 2.5 petabytes (2500 TB) of memory capacity. This number was obtained by estimating how much information can be stored by 125 trillion synapses in the cerebral cortex.

Maybe, indeed, it is not a bad idea to lock myself at home for several weeks, watch the market crash, and re-think where we are, and where this society is going?

Do you know the Java History?

Submitted by moorkristina on Mon, 01/13/2020 - 08:39

We all heard about the popular Java programming language. But few delve into its essence. How is it different from others? What is his story and most importantly how can Java developers help your business and your ideas. In fact, this language is the next iteration in the IT world. Since 1995, it has changed and adapted. Today it is one of the most popular programming tools. Specialists are in great demand and it is not so easy to find someone who can fully realize your ideas and create a quality product. The issue of staff selection should always be taken seriously.

Largest online encyclopedia of physics, math and computing

Submitted by jworkorg on Sun, 01/12/2020 - 08:54

In 2020, HandWiki (https://handwiki.org/) has become the largest online wiki encyclopedia of natural sciences and computing. It has more than 105,000 scholarly articles, incorporating the current Wikipedia articles on many research topics, scholarly articles submitted to the Wikipedia foundation, and various wiki books. For example, the current number of Wikipedia articles on physics is about 12,200 (Jan 2020). In addition to these articles, HandWiki includes about 700 other articles (sourced from different publishes, plus the original articles).

Statistics and simulation show that wealth is just pure luck

Submitted by jworkorg on Fri, 12/27/2019 - 15:35

A recent article  "Talent vs. Luck: The Role of Randomness in Success and Failure" published in  Advances in Complex Systems Vol. 21, No. 03n04, 1850014 (2018) (arxiv.org/abs/1802.07068) shows that, according the a new computer model of wealth creation, the most successful people are not the most talented, just the luckiest.  The developed computer model accurately reproduces the wealth distribution in the real world.

What is standard deviation?

Submitted by James Johnson on Tue, 12/24/2019 - 09:03

Standard deviation in statistics, typically denoted by σ, could also be a measure of variation or dispersion (refers to a distribution's extent of stretching or squeezing) between values during a group of data. The lower the standard deviation, the closer the data points tend to be to the mean (or expected value), μ. Conversely, a far better variance indicates a wider range of values.
