Microsoft Excel is a fantastic tool for analyzing scientific data. Microsoft Word is a fantastic tool for writing up scientific research. So surely Microsoft Office is the only software a scientist would ever require beyond that associated with specialist scientific apparatus? Unfortunately, that has never been the case and most university researchers would identify one big problem with the Office suite and that is why it‘s always been difficult to present formulas in Word and Excel. Even when you type a simple fraction like 3/5, it gets presented on a single line. As for Greek symbols like pi...well, that would mean many hours wasted trawling through Excel‘s Insert Symbol menu.
Just as with HTML editors, various open-source software programs have sprung up to provide an alternative to the dominant player, Dreamweaver in the case of website editors and Microsoft office in the case of office application suites. Whereas in the webpage authoring arena you have NVU, SeaMonkey and KompoZer, in the office application suite you have LibreOffice (formerly called OpenOffice) and NeoOffice.
