So what ? speed is not time or distance, it is something else.

I don't understand this can you rephrase please ? I asked for reference to your source of this alleged data and also most importantly what it refers to. These days it costs millions to build a new school or even refurbish an old one. So are you just referring to the day to day running costs ? Does this include government initiatives to equip/re-equip a school with IT equipment, which happen periodically ? What about all the grant for sports facilities and so on ?

Actually this is not correct. It does correctly suggest that causality (which is a temporal relationship) does restrict time travel, but not space travel, regardless of other considerations. Space travel is not restricted by causality, there is always another factor in play which does this. In the case of your example, your restriction applies to the travel speed, not to the fact that the Earth-Moon distance is traversed. The traverse and murder could easily the accomplished by suitable travel speeds without violating causality.

Sadly I have to report that SF no longer works completely on my Dell desktop windows XP. I can login and read posts OK The system allows me to add rep points. But it does not allow me to enter text into the input editor either to add new posting to existing threads or pms or start new ones. I can enter titles into the title box though. Attempting to use the quote function simply returns me to the top of the page, without adding a quote into the editor. In order type type this in I have had to borrow a windows 10 laptop, not a long term proposition.

Welcome David Oliver and +1 for a good beginning answer to the op. You may have joined at an inopportune moment during updating and spam combat which has been going on over the last few days since you obviously haven't finished your post. I do most sincerely hope you haven't been frightened off by this disruption as SF is normally a much more convivial place for genuine folks. I also like your clear example of general v specific, +1 But I disagree with the proposition that it is impossible to specify a general triangle. One way to do this is to turn to algebraic geometry. A general triangle is a set of the form { (a,b), (c,d), (e,f) } where a,b,c,d,e and f are real numbers. Another way from another discipline would be to say A general triangle comprises three connected words as in the 'health triangle' { social, mental, physical }

First and simplest test. Is the gaussmeter reading the same if you remove the TV from the vicinity?

So ?

What qualifies you to speak 'for the UK' on the matter of education ? Apart from mixing up the words 'private' and 'public' in relation to education, where these wods have special meanings, there are 4 separate education systems extant in the UK, and you have singularly failed to take this into account. I studied trigonometry well before I was 16 and I can safely report that I have needed it pretty well every year of my working life. Please establish this as fact before you start preaching about economics. What exactly do you think this sum covers ?

I agree that causality vitally important. It is also a very slippery concept to define. Indeed +1 But more than this it emphasises that there is a fundamental difference between space and time. Nobody thinks that causality is violated because you can travel in space and kill your grandfather. Modern ideas about paradoxes have led to some interesting connections and the notion of the 'strange loop'. https://en.wikipedia.org/wiki/Strange_loop https://mathworld.wolfram.com/StrangeLoop.html

Hi Dave. New hardware ? I know it's like new tyres on your car. Only car mechanics notice the difference but absolutely essential nevertheless. But how about one of those James Bond Super Anti Spammer Lomg Range Lasers ? (JB-SAS-LRL)s. On another tack you initially mentioned a privacy/cookie change and I am now seeing a "Privacy and Cookie settings Mangaged by Google" Would you care to tell us anything useful about this ? As I see it there are two fronts of attack. 1.) Checkout the members as they first join. I wonder if several are made at a time from the same IP and if this could be used to suppress some ? 2.) My proposal to suppress actual posts via mod programmable keywords. Anyway thanks for keeping things going. +1

One of these ?

I'm not sure what you mean by 'storm drains', espcially in London or the Thames Valley more generally. A good deal of rainwater finds its way to the highway drainage network, which is the responsibility of the Highway Authority. I'm not sure what car washes you mean individual prive drives or commercial car washing stations which will have interceptors and commercial disposal arrangements. As regards cars the main problem with them is the danger of inflammable petroleum products finding its way into the existing system and causing fires and/or explosions.Petrol Interceptors started to be introduced in the mid 1980s when a BS on the subject was published. I remember designing new highway drainage on new schemes in the 1990s + to include these.

A point. Sewerage is the network or pipes etc, sewage is the effluent the flows through it. Further terms with particular meanings are drain and drainage. I think the British system is not as old as you think and definitely much more complicated than you portray. I also agree with Charon Y that even within countries, arrangements vary from place to place. What is your interest in the subject of wastewater engineering ?

For those that might be interested and have access, There is a new documentary program on BBC4 tonight at 22:00 hours local time, 21:00 GMT on "The sky at Night" series entitled "The Search for Alien Life"

It's been done and translated from German into English by non-AIs (humans).

Feedback The rats are still trying I note that couple of new alphasoup members an hour ago, that joind and came back 3/4 hour later but came to nothing. Then just now another as member joined and successfully posted within 2 minutes.

This is a 20 years on edition with some additional material and comments.

I'm not sure if folks caught my meaning properly. If the word 'airlines' appearing in a new thead title automatically suspended the thread to the mods and the modes could also reactively change this word if the spammer changed to say 'insurance' , wouldn't that make life easier for them ? I have lived very happily for 20 years + without emails entitled ...SEX.... or .....Viagra..... or one or two other things.

Near the top of the page you will find the section the thread is posted in. This is posted in Suggestions, Comments and Support. Click on this and it will take you to a thread list for that section. Against each thread is a number of views counter. Hope this helps I will do a screenshot if you need it, but it is easy to find.

There were 19 views of my earlier suggestion on this matter, but no comments. I hope yours fares better. It is clear that the spammers have cottoned on to the 5 post limit.

All contributions welcome. I'm glad the members are less polarised and more objective than your fears. I think it's too early to assess the depth of polarisation. Hofstadter has some interesting analyses of AI

There are two basic types of bond for atom to atom. Ionic and Covalent. Take your pick ? This appears to be homework and should be placed there please.

I note that the titles in the current spate of spam contain certain words - Airlines, printers ....... My old outlook express allows the use of filters that I can set up to simply block email with titles containing certain words and I see 20 years on viagra still comes in and is blocked. Could the admins write a small routine to perform the same here perhaps dumping/delaying them to a mod queue as is already done for some posts. Especially if the mods could easily add or remove troublesome words as the spammers react ?

Sure but I bet it gives more than just the greenpeace result. And I'm also sure you know how to massage google searches to widen the spread.
