Isaac Newton

The background image on this page is taken from Isaac Newton's famous *"The Mathematical Principles of Natural Philosophy"*,
often referred to as *"Newton's Principia"*.

Section VIII, *"Of motion propogated through fluids"*, has a number of "Propositions" one of which
(Proposition XLI, Theorem XXXII) states that "a pressure is not propogated through a fluid in rectilinear directions unless
where the particles of the fluid lie in a right line".
This statement is accompanied by the
sketch included here.

Quoting from the original:

"Let a motion be propagated from the point A through the hole BC, and, if it be possible, let it proceed in the conic space BCQP according to right lines diverging from the point A."

A code refresh...

You:

You have millions of lines of carefully debugged mission critical engineering software. Much of it in Fortran. It's hard to run. But it's too important to ignore and too 'black box' to rewrite.

Us:

We're *proper* engineers with things like PhDs in Fluid Mechanics and Thermodynamics and years of experience in writing complex engineering software.
We specialise in taking your mission critical black boxes and wrapping them up in web services and HTML5 front ends.

So, keep your Fortran as it is and let us provide you with a web service and some HTML5/Angular that'll make your code accessible in the modern world.

Elegant web pages

You:

You need to deliver complex equations to your users. A bitmap copied from a Word document just doesn't look 'right'.

Us:

Decent equation handling is a late addition to web browsers but it is finally here. For example:

$ \rho \left( \dfrac{\partial u_x}{\partial t} + u_x \dfrac{\partial u_x}{\partial x} + u_y \dfrac{\partial u_x}{\partial y} \right) = - \dfrac{\partial p}{\partial x} + \mu \left( \dfrac{\partial^2 u_x}{\partial x^2} + \dfrac{\partial^2 u_x}{\partial y^2} \right) + \rho g_x $

$ \rho \left( \dfrac{\partial u_y}{\partial t} + u_x \dfrac{\partial u_y}{\partial x} + u_y \dfrac{\partial u_y}{\partial y} \right) = - \dfrac{\partial p}{\partial y} + \mu \left( \dfrac{\partial^2 u_y}{\partial x^2} + \dfrac{\partial^2 u_y}{\partial y^2} \right) + \rho g_y $

We can help with layout, setting and proofing.

Useful web pages

You:

Your users want in-line equation solving.

Us:

Some genuine Rocket Science: $F = ma$

Results : Warning - the input has changed! Rerun the calculation

And the answer is... Force = {{o.F}} N

Make your equations come alive...
