A Quantum Summer – by Daniel Powell

The fusing ball we call the sun shines down, it’s rays a warm embrace, The EM radiation passes through, a quantum symphony of grace.

The air is filled with longitudinal waves and song as birds chirp merrily, bees are buzzing at 800Hz and kinetic energy rustles through the trees.sun

The world is awash with a spectrum of light, The 525 nm of the trees, The 420 nm of the sky and 650nm of the flowers around us.

Our Universe is such a place a quantum possibility with the potential for our star, sol being either on or off, or maybe neither?

However, for us being larger than your average electron can always be approximated to a hot sweaty lump of biological matter just soaking up the EM radiation as all of the wavefunctions have collapsed.

Welcome to Animated Science

Dear Readers,

I started Animated Science in 2003 as a small flash-based site for my own pupils. I am now serving Science, teacher training and food-based blog content around the world with an ever-increasing footprint.

It has been over 20 years now online and the changes have been massive, but I try to keep up and serving free content for all users. I serve over 200,000 pages a month from this site alone. The reach is global with many countries using the content but mainly the traffic is from the UK, US, Philippines, India, UAE, Australia, Sweden, Canada.

My site is a non-profit concern, and all resources are provided free of charge and should not be commercially exploited in any way. The ads I have all pay for the hosting and features on the site, so it really is a super Physics resource for all to use.

I also run other content channels in addition to this WordPress based site, please feel free to subscribe and support me. 

Thanks

Daniel Powell

Animated Science Director

Brain imaging study finds that teaching maths to less anxious students helps!

https://www.psypost.org/2021/05/brain-imaging-study-finds-that-teaching-math-anxious-students-to-reframe-their-anxieties-improves-their-performance-60954

This is super research and fits in with what I see daily in Physics.

The idea that if you are stressed you do worse at the mathematics components I think it’s key for Physics. This is why for nearly all my work I give full answers in printed or electronic form and allow my students to read what they want at their own pace.  I avoid excessive questioning in front of the class and make it low stakes.

If you are learning through written questions or works well. a most pupils then slowly learn without stress at their own pace.

I think we all need to move to this type of work and forget a lot of what has gone on for many years. If you want to pressure a pupil give them a proper test in exam conditions. This of course has it place too, but in the classroom normally, Physics is about practice and not stress!

The first room-temperature superconductor has finally been found

It’s here: Scientists have reported the discovery of the first room-temperature superconductor, after more than a century of waiting. The compound conducts electricity without resistance up to 15° C, but only under high pressure.

The discovery evokes daydreams of futuristic technologies that could reshape electronics and transportation. Superconductors transmit electricity without resistance, allowing current to flow without any energy loss. But all superconductors previously discovered must be cooled, many of them to very low temperatures, making them impractical for most uses.

Now, scientists have found the first superconductor that operates at room temperature — at least given a fairly chilly room. The material is superconducting below temperatures of about 15° Celsius, physicist Ranga Dias of the University of Rochester in New York and colleagues report October 14 in Nature. However, the new material’s superconducting superpowers appear only at extremely high pressures, limiting its practical usefulness.

Dias and colleagues formed the superconductor by squeezing carbon, hydrogen and sulfur between the tips of two diamonds and hitting the material with laser light to induce chemical reactions. At a pressure about 2.6 million times that of Earth’s atmosphere, and temperatures below about 15° C, the electrical resistance vanished.

Superconductors and magnetic fields are known to clash — strong magnetic fields inhibit superconductivity. Sure enough, when the material was placed in a magnetic field, lower temperatures were needed to make it superconducting. The team also applied an oscillating magnetic field to the material, and showed that, when the material became a superconductor, it expelled that magnetic field from its interior, another sign of superconductivity.

The scientists were not able to determine the exact composition of the material or how its atoms are arranged, making it difficult to explain how it can be superconducting at such relatively high temperatures. Future work will focus on describing the material more completely, Dias says.

When superconductivity was discovered in 1911, it was found only at temperatures close to absolute zero (−273.15° C). But since then, researchers have steadily uncovered materials that super conduct at higher temperatures. In recent years, scientists have accelerated that progress by focusing on hydrogen-rich materials at high pressure.

Animated Science GCSE 1 to 9 Methods Summary

Animated Science 1-9 GCSE Practical Methods

This booklet of Methods is a simple reference point for the 1-9 Physics GCSE Required Practical methods.

Often questions will be based around these themes and you must learn to interpret the questions on the day as they will try and put them in unfamiliar situations.

This booklet is not designed to teach you everything in the practical’s but to be used to recap what you have already done in class. I have limited most topics to 1 or 2 pages of the bare basics.

You must be able to recall all this booklet and the ideas in it if you want to be able to answer some of the questions in your exams.

They are sure to ask about at least 2 of these topics, and most likely 4 or 5 topics in details so time spent on these topics will stand you in good stead.

Try and use this booklet as a starting point and then read more around the subject and tackle some exam questions to help you out.

I have also included some more help on each of the Key Terms you need to know as well. It can be viewed as a PowerPoint or PDF….

iGCSE Household Electricity

If you want to do a lesson on iGCSE Electricity 2.2 understand how the use of insulation, double insulation, earthing, fuses and circuit breakers protects the device or user in a range of domestic appliances.

Here are some resources to help you. I have attached all the lesson slides and if you work through this, you can then do an iSpring Quiz.

Holst Planets Suite & Nocturnes – Gloucestershire Youth Orchestra 1994

This post is to celebrate a moment in time from 1994 when Gloucester Youth Orchestra played at Cheltenham Town Hall. On this occasion a recording was taken on DAT tape and some copies made for the players to listen to their own music.

Having had this tape cassette in my car for the past 10 years or so I decided to digitise the whole concert so it was preserved for the rest of time on youtube.

I have not altered the recording or cleaned up any noise so please realise this is not a perfect recording but simply a memory to share with any of the other players at GLO at that time, and also for future musicians to be inspired.

I have included an image of the full orchestra compliment which also included some guest players on the day.

It is also interesting to see that many of the orchestra have carried on their musical careers after the orchestra. To name but a few…

Charles Peebles who has gone on to conduct many other orchestras in the past few years.

Matthew Elston who now plays as Principal 2nd violin of the BBC Concert Orchestra and teaches music

Diggory Seacome – musical director – went on to become a Conservative Councillor!
