About CalQlata

Over the years, CalQlata's engineers have used and devised many technical formulas and are now keen to make these available in an accessible and useable form to everyone who may not have the time, resources or ability to learn or develop such formulas for themselves.

Remember, it isn't the formulas and calculations that are important: it's what you do with the answers. You don't need to be technically competent to know how best to handle these. It is to everyone's benefit if the non-technically minded have equal access to technical answers.

Technical problems are not as difficult as you think...

We want to dispel the myth that technical subjects can only be of interest to a select few. Too often, technicians present their work in a form that deters mere mortals from attempting to understand them and formulas can terrify the uninitiated.

Our Approach: Simplification

CalQlata's engineers believe that technical subjects written in a reader-friendly manner would attract more interest and that if calculation tools (software programs) were sufficiently user-friendly more people would apply them.

With this in mind, we remove complicated formulas from view and restrict simple formulas to 'Help' sections and Appendices where those with an interest in detail can access them. We also try to employ everyday language and minimise the use of specialist terms and acronyms. Where the use of such terms cannot be avoided we have provided a definitions page that is accessible in the menu on the left-hand side of every web page. There will also be a link to its definition (e.g. proton) the first time such a term is used on any page.

CalQlata is not only targeting the less technically minded, however. We also provide sufficient technical references to assist those who wish to delve deeper into a subject or find the formulas for themselves.

Our Disciplines

We have no preferred subject or category. Whilst we will cover engineering, physics, mathematical, technical and chemical subjects with equal fervour, we will initially concentrate on those with which we have had most experience to date: engineering and mathematics.

Our Aims

Our aim is to make our calculators as simple, flexible and user friendly as possible in the hope that they will encourage you to 'have-a-go' and, where possible, help you select the correct calculator and input variables from this website.

Although we have a preferred format, designed to: minimise screen use, eliminate unnecessary embellishments and highlight incorrect or inappropriate data entries whilst giving you the freedom to enter anything you like, we realise that the world out there may have other ideas.

Your feedback is valuable to us!

If you think we can improve our calculators or Help-Text, please let us know. Customer suggestions regarding operational improvements or technical corrections are always welcome.

PhD Topics (independent study)

CalQlata believes that much scientific research is carried out today purely for the benefit of its sponsors and therefore reaches biased (e.g. wind turbine generators, Batteries, Diesel, etc.) or even incorrect (e.g. atmospheric CO2, holes in the ozone layer, etc.) conclusions. Whilst misrepresentation may be considered acceptable for many scientific subjects, it should not be acceptable for those that affect all of us, e.g.: environment, medicine, life, transport, physics, etc.

CalQlata has included 'PhD Topics' on this website to highlight a few subjects we believe are sufficiently important (e.g. unification theory) or interesting (e.g. the reason for the Deccan Traps eruption) to warrant independent research whereby conclusions are not distorted for political and/or financial gain and made freely available to all.

CalQlata suspects that PhDs might be the only remaining independent research platform, as such we would like to encourage their use for our suggested topics.

According to convention, a PhD dissertation must contain a "substantial, original contribution to knowledge". CalQlata believes that a further two qualifications should also be applied:
1) "The knowledge must be generated independent of influence from those with a vested interest in the outcome"
and;
2) "The subject matter should be useful to life on earth"
