Formulas are powerful tools for performing calculations and analyzing data in Excel. In this beginner’s guide, you’ll learn how to use formulas (with or without help from the Copilot AI assistant) and ...

Encryption systems rely on “random” numbers, but conventional computers can’t generate them perfectly. New research shows that quantum physics can. By Alexander Nazaryan Researchers in Switzerland ...

Most digital security relies today on random numbers to generate cryptographic keys. Think of a cryptographic key like a long, complex password. If that password is truly random, an attacker has to ...

The power of Python trumps Excel workbooks.

One of the hardest things to do in physics is to generate true, provably unpredictable randomness. That's because it's impossible to determine randomness based on the output alone. The difficulty lies ...

Even the most modern random number generators do not produce perfectly random numbers, which can be a problem for cryptographic applications. ETH Zurich researchers use entangled superconducting ...

In this tutorial, you'll learn how to generate scannable barcodes in Excel in two simple steps. You will also learn how to create random barcodes. A barcode is a machine-readable representation of ...

If you have encountered the error message “There’s a problem with this formula” in Microsoft Excel, you are not alone. Many users report this error appearing ...

These tricks show how AI tools, new import formulas, and classic features improve productivity. Excel has outlasted many tech trends, and in the age of AI, it remains very much in the mix. While new ...

Eeny, meeny, miny, mo, catch a tiger by the toe – so the rhyme goes. But even children know that counting-out rhymes like this are no help at making a truly random choice. Perhaps you remember when ...
