Chemistry / Re: Why adding a fizzy drink to ice does the temp drop below the temp of the ice?

« on: 01/03/2023 11:47:16 »

I heard that

Have you checked to see whether it does?

I can see why the evaporation of CO2 will reduce the temperature, with or without the ice.

nooo, of course not, I'm a sheepy ! it's why I ask the esteemed academia that reside here 😊

Atacama Lagoon and Sagittarius Arm of the Milky Way
Photographer: Alexis Trigo (alexistrigot@gmail.com) 
Summary Author: Alexis Trigo (alexistrigot@gmail.com) 

Despite being the driest place in the world, the Atacama Desert has several lagoons, created by groundwater, in the vicinity of the Atacama Salt Flats. When night falls and with no wind, the lagoons become true mirrors for astronomical observation. Shown over the un-named pond featured here is the Sagittarius Arm of the Milky Way.

Fortunately science can come to the aid of our ovine correspondent.

Those of us of a crystallographic or medical imaging persuasion spend a lot of our working lives in k-space where the infinite becomes infinitesimal and teeny weeny ripples in the microcosmos are big enough to see.

Any tourist who is overwhelmed by the Grand Canyon is welcome to visit the road from my house to the research park, and study hundreds of natural canyons formed by the confluence of British council officials, British contractors, and British weather. The canyons are just big enough to destroy an alloy wheel or kill a cyclist. There is an annual ritual of "closing the road" just before the end of the financial year, and a few months later a whole new crop of canyons appear, so it's much more dynamic than its transatlantic counterpart, which hardly changes from one century to the next.

I believe work is already in progress to reform the minute, and the abolition of the leap second has already removed one of life's uncertainties. There are however opposing views on the next phase: when I say "just a minute" The Boss starts nagging after 30 seconds, but when she says it, it means as long as it takes to complete a telephone call, feed the dog and change handbags. I think the compromise might be to lengthen the second.

AFAIK there are no ethical objections to resurrection, and there is even a choice of procedures. Christians of my acquaintance are certain that their entire bodies will be restored to life at some time in the future, and adherents of other faiths are certain that minds and spirits are routinely reincarnated on a daily basis, though not necessarily in the same species. So the broad consensus is that Sir Isaac may indeed already be present as a crab louse or  tapeworm, or if not, he will turn up eventually at the same time as everyone else.

The thought that Sir Isaac could well be a part of my gut bacteria is comforting and explains my healthy bowel movements  !! lol

if it is not imposing too much, I would dearly love to see some pictures of your locality.....making me very jealous here as a suburban sheepy of London Town.

Chemistry / Why adding a fizzy drink to ice does the temp drop below the temp of the ice?

« on: 25/02/2023 18:22:07 »

Dearest Peeps who know oh so much !


I heard that when you add a fizzy drink to ice, the drink actually gets colder than the ice is  !!  What is it with this evil sorcery !!!!!


Why's that then ?....Could we continually add more and more till we reach absolute zero ?


so:


Why when adding a fizzy drink to ice does the temperature drop below the temperature of the ice ?

Physics, Astronomy & Cosmology / Re: How Do We Know The Universe is 13.8B yrs Old If We Can Only See The Observable ?

« on: 25/02/2023 18:09:21 »

How can we know it is 13.8 billion years old if all we can see is the observable Universe ?

The age was not computed by looking as far as we can see. Hubble's constant of about 70 km/sec/Mpc was measured nearly a century ago, long before they were looking at things a significant percentage of the distance to the edge of the observable universe. The age can be computed directly from just that one constant.

There's about 3e19 km in a Mpc, so 70 km/sec/Mpc is the same as 2.3e-18 km/sec/km which, cancelling the km part, is 2.3e-18 sec^-1
The reciprocal of that is 4.35e17 seconds which is 13.8 billion years.

Thank you Halc, so, even though we have no idea how large the unobservable Universe is, we can still take an educated guess and infer its existence , age and properties through indirect observations. woooooo !!!......

Hi, I'm Sheepy how are ewe ?


As a keen Astro photographer I am proud to have the record for the most pretentious "selfie" of all time.





Trust me, It was rather hard holding the selfie stick for this one !!


In the above non-doctored-bona-fide-true-to-scale photo I was contemplating on the age of the Universe.  How can we know it is 13.8 billion years old if all we can see is the observable Universe ?


How can ewe deduce the age of the Universe if ewe can not see the unobservable Universe in all its non viewable grandeur ?


**As a firm believer in empirical study I sneaked into my neighbour's house at 3am this morning and he gladly did not resist when I chloroformed him. I strapped him to a firework with a piece of foil (solar sail 2cmx 2cm)  attached and launched him. I told him that all he need do is hold his breath and to not let go of the end of the tape measure and stop watch,  Whilst we await the data can you answer the kweschun ?

Non doctored  true-to-scale (1-1) bona-fide image of my sandwich just moments ago.

Intriguing.

A publisher's photographer of my acquaintance reckoned to spend half a day to photograph a sandwich lunch to the satisfaction of the editors, and by the time  they had added glosses, moisturisers, citric acid or sodium bicarbonate in all the right places, it was inedible.

They should have employed a sheep.

Alan, I have been ostracised by the food-photogrpahy industry as my techniques are too competitive !

If I have a stack of sandwiches to cut, I do them one at a time, cutting them all in one just squashes them. I cut by rolling the curvature of the blade, drawing the blade across them just tears.

yes, yes, this is what I do. I do not use a bread knife for this. Thank you vhfpmr

The top slice stops all the loose bits from flying about when the knife tears them. It's a craftsman's trick to sandwich fragile materials  between sheets of scrap plywood when cutting complex shapes.

Late in life I have discovered that a simple vertical press with a Chinese chef's chopper cuts sandwiches much cleaner than sawing with a bread knife.

Thank you Alan. lol.."chinese chef's chopper" lol...smirk  guffaw !!

Well for one, the only people I've known to cut the cheese do so between two buns.

That out of the way, it's probably because the hoagie roll provides a nice dry handle of sorts, providing a nice reaction force to what the knife is doing. Sans roll, you'd have to get the slimy parts all over the trotters, far more difficult to hang on.

Thank you Halc.  I think there's a niche in the market here for a new invention !

As a sheepy I of course know all about pulses, I am an expert having had a pulse all my life.


One thing I was recently made aware of is that the Earth has a 26 second pulse !!!...what's that all about ?


Please deliver me an answer as I am about to become a first aid sheep and I need to know how to resuscitate the Earth should it it's pulse weaken or even stop !!




so, What Is The 26 Second Pulse Of The Earth ?

Dear Sir/Madam,

I am writing to express my disappointment that Sir Isaac Newton was not born in this century. I understand that he lived in the 17th century and made many significant contributions to science and mathematics, but I believe that his presence and knowledge would be invaluable in today's world.

To resolve this issue, I suggest that we consider the possibility of reincarnating Sir Isaac Newton. This could be done through advanced scientific methods such as cloning or genetic engineering, or even through spiritual means. By bringing Sir Isaac Newton back to life, we would have the opportunity to benefit from his incredible knowledge and genius in a modern context.

I understand that this is a complex and unconventional solution, and that there are likely to be many ethical and scientific hurdles to overcome. However, I believe that the benefits of having Sir Isaac Newton back with us in the present day would be immeasurable and well worth the effort.

Thank you for your time and consideration.

Sincerely,

Dear Sir/Madam,

I am writing to express my frustration with the current standard of having 60 seconds in a minute. I believe that this number is too high and causes unnecessary stress and time constraints in our daily lives.

I understand that the concept of 60 seconds in a minute has been widely accepted and used for centuries, but I believe it is time to reevaluate this standard. Perhaps reducing the number of seconds in a minute would make time feel less rushed and create a more relaxed pace of life.

I hope that you will take my comments into consideration and consider the possibility of making a change to the current standard. I understand that this is a major change and would require a great deal of effort and coordination, but I believe that the benefits would be well worth it.

Thank you for your time and consideration.

Sincerely,

I am writing to express my disappointment about the Grand Canyon being too wide. I understand that the Grand Canyon is a natural wonder and its width is a result of millions of years of erosion, but I feel that it is too overwhelming and difficult to take in from one viewpoint.

To resolve this issue, I suggest that the National Park Service consider narrowing the Grand Canyon. This could be done by adding natural barriers, such as rock formations, along the rim of the canyon to create a more intimate and manageable viewing experience for visitors.

I understand that this is a bold suggestion and that there may be concerns about the impact such a project could have on the natural environment. However, I believe that with careful planning and consideration of the environment, it is possible to create a more manageable and enjoyable experience for visitors while still preserving the beauty and majesty of the Grand Canyon.

Thank you for your time and consideration.

Sincerely,
