I'm starting to doubt myself, but that was my understanding too. Furthermore "..." denotes a direct quote, whereas '...' can mean that the quote is indirect/paraphrased.

Googling "MCB-OD crossings" will bring up various pages and videos that show such crossings in the UK. They are relatively new to the UK but I believe they have been used for some time in continental Europe. They have disadvantage

In the UK many crossings have full width barriers, and must be confirmed to be clear of road traffic after the barriers have closed before the protecting signal can be cleared for a train. These are effectively fail safe. Confirmation comes

In the case of Mathematica, 1-based indexing also makes sense in the context of it being a lisp-like language where everything is an expression that can be represented as a tree. So in the case of exp = x + y + z this is syntactic sugar for

Variable gauge trains help overcome this problem: https://en.m.wikipedia.org/wiki/Variable_gauge I once took a night train from Barcelona to Paris that changed gauge at the border. It slowed to a walking pace and trave

Brexit to some Brexiteers means what they rather fancifully believe is the 'clean break' of no-deal. To some other Brexiteers, Brexit means continued membership of the customs union, but not the single market. No doubt that there

The proposed key-value function database mentioned in the article sounds like the recently launched Function Repository in the Wolfram Language... https://resources.wolframcloud.com/FunctionRepository/

I came across Mathematica via Wolfram Alpha while studying for a Maths degree. I was quite astonished by its capabilities, and have been playing with it ever since. For context I work full time in an industry unrelated to software, and have

I did my BSc in Mathematics with the OU. Overall it was a very good experience. Rather than teaching by lectures, the OU provides you with high quality and substantial written materials. As with any other university you are expected to keep

Mathematica interprets the real numbers 9999999999999999.0 and 9999999999999998.0 as having machine precision. To work in arbitrary precision, you need a backtick after the number, followed by the number of significant digits. In this case,

McDonald's double espresso poured over a 99p sundae (plain, just ice cream) makes for a decent cut-price affogato.

Regarding the double brackets for representing Part, you can instead use〚 and 〛which can be input with `ESC`-[-[-`ESC` and `ESC`-]-]-`ESC` respectively. This makes the code prettier and easier to read. There is a very easy to implement modi

I suspect that the OP used the "Print..." command in the File menu, and selected PDF as the printer option. ISTR that this can sometimes result in poor quality results as presumably it is relying on an external PDF engine to rende

Pret is dismissed early in the article, but having previously been an espresso lover, I'm now hooked on Pret's filter coffee. At 99p a cup it has the best bang for buck of any takeaway coffee, and although I occasionally encounter
