Today I saw a documentary program on television proposing politicians to be robots running artificial intelligence. It left me thinking...

The surface of seas would be covered by a poisonous gas layer if Cl volatility happened.

That clear compound used to cover porcelain, pottery, yielding a very hard surface after the kiln process... What is it made of ? It is sold as a thick liquid ?

Did someone 'pulled my leg' a looong time ago telling me these were to detect 'illegal/undisclosed' transportation of radioactive materials ? Or are those only mass detectors, speed detectors, vehicle counters, toll transponders... ?

Something like these crucibles ? ----> https://duckduckgo.com/?q=ceramic+crucible&t=canonical&iax=1&ia=images

That is capacity four. You can install capacity ones inside these booths every block or in front of boutiques, or in offices, the barber shop, no parking needed... Just dial its number and you show up there :

With few working satellites in orbit yet, is the Galileo working today, even with delayed capture, or poor precision, or both ?

Nothing better than ---->

A bicycle, hanged off ground. Wheels turning. No or fixed steering, (or, both wheels on a rigid frame.) Trying/pushing to 'topple' it, some torques become active. If the wheels are turning in opposite directions, What torques/forces to expect trying to topple it? Next... wheels with their shafts at a right angle. What torques/forces to expect trying to topple it? Next... 3 spinning wheels with their shafts in the 3 axis. What torques/forces to expect trying to topple it?

That gold mined centuries ago since ancient times, the gold from spaniard conquerors, the gold from mines production in all continents. Physically, where is it ? Cannot believe that a substantial amount is in jewelry or museums. The amount of gold produced in say 3000 years, has to be a huge amount. Where is it now ?

Perhaps this could be in chemistry... Please move if needed. Latex gloves have a short life, degrade in air, and perhaps in contact with some liquids. Nitrile gloves, and other materials gloves in the market... Which one has the longest duration -not puncture related- ? Need to save certain small items inside cut-off fingers off flexible gloves, sealed; and looking for longest life material. Any suggestions ?

That is not the point. Not concluding anything but asking. Here is one : ----> http://corpus.quran.com/translation.jsp?chapter=5&verse=51 If a Quran follower is prevented by the Quran from being peaceful and friendly towards other religions, is the peaceful follower acting against the Quran ?. Yes, No, or no answer.

Hi. After a peaceful follower of the Quran reads (Surah 5:51) (Surah 2:191-193, 216-218, 244) (Surah 3:157-158, 169, 195) (Surah 4:71-74, 84,91) (Surah 5:35) (Surah 8:12, 17, 39, 60-65, 74-75) (Surah 9:5, 14, 20, 24, 29, 36, 38, 39, 41, 73, 111) (Surah 22: 58, 78) (Surah 25:52) (Surah 29:6) (Surah 47:4) (Surah 61:4, 11) (Surah 66:9) ----> Disobeying these above, by being peaceful towards other religions means going against the Quran ?

Design, develop and conduct an experiment / device to measure the propagation speed of gravity.

Seems every culture/nation wants / has developed its own 'dialect' I believe there is an international sign language, at least in intentions. Can a deaf person that only knows a particular variation of sign language from his country, understand a 'decent' amount of international signs to carry a cross conversation ? If such international language was someday a reality; could it bypass spoken languages as a -say chinese- sustain a sign conversation with a -say hebrew- ? And all other cultures permutations, without learning all the involved spoken languages themselves ?

English... if the thread title was, instead, LEDs mimicking sunlight ; would it have the same meaning ? Better ? Worse ?

Superb craftsmanship worth sharing. Enjoy : ---->

In other forums that use this same 'architecture'; when being logged-in times out, all typed contents in the reply box get saved automatically, actually happens every minute while logged; and reported being so. After re-logging-in, prompts the choice to restore saved content. That saves a lot of frustration from losing very elaborated responses wiped out to never recover. Perhaps that feature is hidden to be implemented among all the tweaks.

Hi. What did all those indicator lamps tell the operator ? The buttons, knobs, dials, selected what ?

Thanks. Yes, iron in 6+ metres long bars can be an ohm or two more resistive than copper. Which I suspect of little effect in huge voltages, as the high tension transmission lines behave to minimize losses with other than copper. Yes, the conductor is the one more likely to be hit instead of the building. So see no downsides ? Other than more often soiled pants from the much louder and sudden thunder scare originated a few metres away...

Hi. Lightning rods, with their properties of attracting and providing a safer electrical path to ground have their advantages to prevent a house to burn or the unpredictable damages caused by a lightning bolt. Is there any cons; like -say having them installed will promote more hits to the dwelling rod, instead of less hits that may be diverted to nearby trees or other buildings ? Would the hits be much less destructive, but more frequent ? For the brutal voltages involved; would a plain reinforcement iron bar as rod and path to proper grounding instead of a 1/2" copper path be reasonably comparable ? A 1/2" 'rebar' tiny additional resistance to the brutal strike voltage should not be significantly detrimental, is it ? (This is not about using the structural 'rebar', but as an external path)

Seems posts are not numbered any more. Or I could not see such. Could help for referencing as before. Also, from the previous board version, as I was caught in the transition posting : Are social networks still intruding or just not shown now ?

Triple backup current contents first ! Wait for Murphy to get sedated. Thank you.

Which illusion, performance has impressed you the most ? That unforgettable one that dropped your jaw to the floor and still has you scratching your head ?

Good if those records being a copy in an internet-exposed read-only computer/server. Not the protected main computer kept in safe isolation from crooks, which find how to become 'approved personnel' and spread their diarrhea everywhere.
