Periodic table of the elements software. In addition to the usual information found in such programs, it also contains a wealth of nuclear information on each isotope, including half life, decay mode, and daughter products. X-ray data (fluorescence and binding energies) is included, as well as photon interaction values. Electron shell and particle energies are also listed, along with visible spectra, and a table of wavelengths and amplitudes. Theres a handy chart of the nuclides, showing all of the isotopes included in the Atomic Mac periodic table, about 1600 of them! Clicking on one takes you to detailed data for that isotope, such as half life, decay mode, alpha/beta/gamma energies, and daughter products. A molecular weight calculator makes it easy to find the molecular weight of compounds. A shaded diagram showing the ranges of physical properties makes it easy to visualize relationships across the periodic table.

<<lessMacJanitor 1.3
MacJanitor is a freeware utility to run the systems daily, weekly, and monthly maintenance scripts more>>
MacJanitor provides a way to run system maintenance tasks at the click of a button.
The Unix subsystems on Mac OS X were originally written for machines that were typically never shut off. Mac OS X inherits this assumption in version 1.x, and has many system maintenance tasks that are scheduled to run between 3 am and 5 am. In addition, there are scripts designed to run weekly on weekends, and once a month in the middle of the night.
If these maintenance tasks are never run (such as on a laptop that is always shut off at night), many log files and system database will grow extremely large or fail to get backed up.
Laptop users could click the daily button every morning (or every few days), or office workers could click the weekly button on Mondays.
If youve been leaving your machine off at night without allowing the maintenance tasks to run for several weeks or more, the first time you run them using MacJanitor may take several minutes. Also, if your log files have grown extremely large and you are low on disk space, the tasks may have problems moving the files around and compressing them. After that, it typically takes less than a minute for each task.
The output of the task is displayed in the scrolling view in the bottom part of the window. If for some reason you feel the need, you may print the output of the system maintenance tasks (but why?...).
Enhancements:
- Built for Panther and higher (Tiger compatible).
- Uses the periodic tool instead of running the tasks directly.

Periodic Table - A very useful and highly functional periodic table. more>> Periodic Table - A very useful and highly functional periodic table.
Our Periodic Table application was designed with ease of use in mind, and elements can be viewed in many different ways:
- Traditional table, colour coded with atomic numbers
- List view, both names and symbols in alphabetical order
- Sort view allows the elements to be sorted based on their numerical data, from boiling point to atomic radius
Elements can be selected from anywhere in the application, showing a detailed view of its attributes.
The Periodic Table is completely free of charge, although a huge amount of time was put into making it, so donations are greatly appreciated.

TablePod 1.3 is a simple to use, yet sophisticated utility for the chemistry student or maybe the professional chemist.
It gives you a periodic table of the elements on your iPod. TablePod, is different from the other (one, maybe two?) as it gives you a visual table. Each elements has its own image. The elements backgrounds have a color that corresponds to the type of elements (Alkali Metal, Noble Gas, so forth). For now TablePod is for quick reference, it has name, number, symbol, weight, and type.

Anacron 3.3
Anacron runs the periodic scripts even when the machine is frequently asleep or off. more>>
Runs the periodic daily, weekly or monthly tasks on your Mac even if the machine (a laptop, for example) spends much of its time either asleep or switched-off. Anacron checks when you reboot and every sixty minutes while the machine is running and to see if the various periodic scripts are overdue, and runs them if necessary. It runs automatically, requires no operator intervention, and will run both the default daily, weekly, and monthly scripts and any local additions.

JAW PseudoAnacron - Performs missed periodic maintainance tasks more>>
You can find utilities around the net that allow you to manually launch those tasks, others (like anacron) that, once installed in the system, are repeatedly called to check any skipped cron task.
PseudoAnacron takes a different approach: at login (its a startup application) it checks if the periodic daily/weekly/monthly task was skipped and in that case the task is launched; after that, PseudoAnacron quits, wasting no more CPU cycles.

- Universal Binary.
