How Do the Chemicals in Sunscreen Protect Our Skin from Damage? Kirrawee high physics. Sunspots are regions of much higher magnetic field, and lower temperature, on the surface of the sun.

They occur in an eleven year cycle, and effect our planet through the solar wind. Powerpoint slides When things are at different temperatures they emit different wavelengths of light, for example a piece of steel will pass through a number of colours as it is heated. The same is true of stars, and of the entire electromagnetic spectrum (not just visible light). We can use this fact to determine the temperature of the star. Powerpoint slides. Step Up In Education. Current and charge. These activities will help students to relate the idea of current (as shown by an ammeter) to the idea of electric charge (more familiar from experiments in electrostatics).

Current and charge

Electrolysis links these two by showing that, the greater the current that flows, and the longer it flows for, the greater the mass of material released. Experiments Series and branching circuits. Year 12 HSC Physics - Practical Work. More often than not, practical work in Physics will involve determining and using the mathetical relationship between two variables: the independant and dependant variables.

The material below describes how such an investigation would be carried out and what to include in a write-up of the investigation as a report. Key Terms. Scientists turn mammalian cells into complex biocomputers. Computer hardware is getting a softer side.

Scientists turn mammalian cells into complex biocomputers

A research team has come up with a way of genetically engineering the DNA of mammalian cells to carry out complex computations, in effect turning the cells into biocomputers. The group hasn’t put those modified cells to work in useful ways yet, but down the road researchers hope the new programming techniques will help improve everything from cancer therapy to on-demand tissues that can replace worn-out body parts. Engineering cells to function like minicomputers isn’t new. As part of the growing field of synthetic biology, research teams around the globe have been manipulating DNA for years to make cells perform simple actions like lighting up when oxygen levels drop. To date, most such experiments have been done in Escherichia coli and other bacteria, because their genes are relatively easy to manipulate.

Scientists have tried to extend this to mammalian cells to create genetic circuitry that can help detect and treat human diseases. Not one, not two, but five new particles discovered with the Large Hadron Collider - ExtremeTech. Operating at unprecedented luminosities, the LHCb experiment at CERN has revealed a system of five “glue-like” particles that interact through the strong and weak nuclear forces.

Not one, not two, but five new particles discovered with the Large Hadron Collider - ExtremeTech

The particles are called glue-like because they’re expected to shed light on how quarks bind together. This discovery could help us to fill out a “periodic table” of subatomic particles. This discovery was made possible thanks to the large dataset accumulated during the first and second runs of the Large Hadron Collider. With so much data — really, the LHC’s cup runneth over with data because of all the collisions they’ve been doing — scientists were able to isolate the signals from the system of particles with high confidence. Unlike prior false alarms, this is no statistical fluke. According to CERN: The particles were found to be excited states – a particle state that has a higher energy than the absolute minimum configuration (or ground state) – of a particle called “Omega-c-zero”, Ωc0. Forces and motion. Missmunchie - Profile. 'Physics-defying' gravity hills are one of the strangest natural phenomena we've seen. Scattered across the world are a number of bewildering 'mystery spots' that appear to defy gravity - places where cars seem to drift uphill, and cyclists struggle to push themselves downhill.

'Physics-defying' gravity hills are one of the strangest natural phenomena we've seen

There are reportedly dozens of gravity hills around the world, in the US, the UK, Australia, Brazil, and Italy, and they all have one thing in common - if you drive your car to the bottom of the hill and put it in neutral, it will proceed to roll back UP the slope. Check out this car on a gravity hill in Aryshire, Scotland: Science Channel You can literally get out of your car and watch it drift up and away. This YouTuber sent a ball down a road in Pennsylvania, only to have it roll back up the hill towards him: Phenomenal Travel Videos.

You don’t have to be an aeronautical engineer to know that an airplane cabin is pressurised to keep us from passing out as we soar through the skies, 11,000 metres (36,000 feet) above sea level.

Gravity Visualized. Scientists have proved that cats understand physics. Which animal do you think is the smartest? It’s a difficult question, of course, because different animals are good at different tasks. For this very reason, Japanese researchers have recently decided to reword the question and find out which animals are better than others at one of the most complex sciences: physics.

And the answer turned out to be cute and fluffy — it’s cats! The classic test of an animal’s ability to find a logical link between events is quite simple. Quarkology - HSC Physics and Chemistry. This crazy new material can trap and recycle radioactive nuclear fuel. All energy-making processes end up taking a toll of some kind on the environment, but the impact is considerably harder to manage with nuclear power, which generates dangerous and long-lived radioactive waste. Now scientists have come up with a new material that could make nuclear fuel recycling cleaner, cheaper, and more effecient. The new material has been identified through a combination of experiments and computer modelling, and is based on what we already know about materials called metal-organic frameworks (or MOFs).

PhysicsLAB Worksheets. Don't be fooled by these common physics misconceptions. We're all pretty used to loling about Flat-Earthers and their crazy antics by now, but the sad truth is that, instead of wasting our time trying to convince conspiracy theorists with, you know, the facts, maybe we should be looking inward, and clearing up some of our own problems with miscommunication in science.
