Formulas Lite, an invaluable math and science study guide

Formulas Lite is a collection of important information and tools to help students get through some of the tougher subjects in school.

Within each of these top-level subjects, formulas are further organized by topic. For instance, under mathematics you'll see formulas organized in branches from algebra to statistics. Under physics, you'll see formulas organized in branches from relativity to torque. Within the chemistry section, you'll also find a functional periodic … Read more

Can the MacBook Air replace the White MacBook? Maybe it's not trying to.

Is the MacBook Air the new mainstream MacBook?

The White MacBook is dead. The cheaper, plastic $999 legacy to iBooks and PowerBooks of old has finally been removed from the spectrum of Apple laptops, and suddenly the decision spectrum has narrowed to two choices: the MacBook Pro, and the thinner MacBook Air, updated this morning with a faster processor and preinstalled with OSX Lion.

The MacBook Air has walked an interesting path since 2008, first as a high-end executive plaything, then a more attainable but still specialty interest ultraportable. Last year's MacBook Airs debuted in October, well after back-to-school shopping.

This year, however, the new Airs have emerged in late July, perfectly timed for students planning their computer purchases. The MacBook Pro, meanwhile, last saw an update back in February.

A $999 MacBook still remains; the 11-inch Air's base model costs the same as that older white MacBook. Its 1.6GHz Core i5 processor feels far zippier than last year's Air, but its limited storage (64GB of flash memory) presents a limit to hold-everything-on-your-hard-drive people. On first boot-up, 48GB of drive space was free to use, which limits what you'd permanently keep on your computer. That 64GB of storage can be expanded up to 256GB at the time of purchase, but that drives the price up, too, by several hundred dollars.

Or, does that matter anymore?… Read more

Great geometry tool

GeoGebra, the free, open-source mathematics software is designed for math classrooms in secondary schools, but anyone who uses geometry, algebra, or calculus should check it out.

Apple's back-to-school deal gets download focus

Instead of offering student Mac buyers a free iPod--as it's done for the past several years--Apple this morning launched its annual back-to-school promotion with a $100 credit for digital downloads.

That $100 can be spent in iTunes, the iBookstore, and in the iOS and Mac App Stores. One trend you might notice there is that Apple's found a way to get a return on that $100, which could be the whole amount if someone ends up buying Apple's own software like iWork and Aperture, which can be found in the Mac App Store. Apple makes 30 percent … Read more

Mediocre school management

We encounter a surprising number of programs that are designed for business use but are themselves somewhat unprofessional. Unfortunately, QZ School Management System Free is one of these programs. Although it seems to have a lot of features at first glance, it has several drawbacks that undermine our ability to take it seriously.

The program's interface somehow manages to be both sleek and cluttered; it has a modern look to it, but each of its tabbed menus contains a whole lot of icons. Once you familiarize yourself with it, however, it's not too difficult to navigate. The program … Read more
