The discussion revolves around issues with LaTeX rendering on older web browsers, particularly in the context of Physics Forums. Participants explore the implications of recent updates to MathJax, the external tool used for LaTeX rendering, and the challenges faced by users on outdated operating systems and browsers.
Participants express a range of views on the necessity of upgrading from older operating systems and browsers, with some advocating for immediate upgrades due to security risks, while others defend their use of legacy systems for specific applications. The discussion remains unresolved regarding the best course of action for users experiencing LaTeX rendering issues.
Participants mention various versions of browsers and operating systems, highlighting the limitations and potential security risks associated with using outdated technology. There are references to specific LaTeX examples that may not render correctly, but no consensus on the underlying cause of the issues is reached.
I haven't had any problems. I'm on Win 10 with Edge as the browser.Greg Bernhardt said:
Can you post the LaTeX here that seems broken for you?Tom.G said:Well, once again someone recently did a 'New and Improved' iteration of Latex and broke it, at least on older browsers.
I've cleared the browser cache (>10 000 files) and refreshed the page, all to no avail.
"The equation F in BSL table 19.2-4 and Exercise 19D.2 seem to suggest that Cp should be evaluated at the existing overall molar composition as ##\sum{y_iC_{P,i}}##.
I should also point out that, in BSL, the molar flux is defined in terms of the mass transfer coefficient by $$\dot{M}_i^"=k_i\left(y_i-\frac{p_i(T)}{P}\right)$$ where ##k_i## has units of moles/m^2s. Under these definitions, the Sherwood number for a porous medium (for use in conjunction with the correlation equation) would be defined as $$\frac{k_iD_p}{(1-\epsilon)cD_i\psi}$$ where, in BSL notation, $$c=\rho_{m}=\frac{P}{RT_I}$$
BSL point out that ##cD_i## is much less dependent on temperature than ##D_i##."
"I have successfully done first order equations before but this one has got me a little stuck. My attempt at the general solution below:
$${5} \frac{\text{d}\theta}{\text{d}t}=-6\theta$$
$${5} \frac{\text{d}\theta}{\text{d}t} =\frac{\text{-6}\theta}{5}$$
$$d\theta = \frac{-6\theta}{5} dt $$
The integral should then = $$\theta = \frac{1}{5} in(5)$$
$$\theta = -6 \times (\frac{1}{5}) in (5) + c$$"

Looks like FF 52.9 (this will be a significant update!) and Chrome 49 are the latest versions for XP which you can update to.berkeman said:

You are using a dozen plug-ins from unspecified authors on an unsupported and insecure version of Firefox running on an unsupported and insecure version of Windows? I suppose next you are going to say you aren't aware of out-of-band security patches such as the Security Update for Windows XP SP3 (KB4500331)?Tom.G said:
I don't know Tom's reason for still using XP, but we do have a handful of old PCs here in the lab still running XP because we have some legacy tools and applications that only run on that old OS. We are not allowed to plug them into the building network, however, since IT obviously considers them a security risk.pbuk said:

There's a reason for that.DrClaude said:
Amen to that!pbuk said:
Re: Gopher and Kermit and modems and Pine. I don't feel that old, but am. Back in the early 90s I was using my IBM-compatible PC at the college I worked at, to connect to the school's mini that was running Unix, so that I could compile some simple C programs.DrClaude said:
