Measuring Granular Flow Through a Funnel with a Force Sensor

Posted on

  Abstract This paper presents an apparatus to measure the flow of granular matter through a funnel with a force sensor. In addition to being easily reproducible, our proposed method enhances measurement accuracy from the popular method that uses a stopwatch. We notice, however, that our proposed setup induces an unwelcome force that confounds force […]

Get excited about the first Northern Conference…but who will be there?!

Posted on

For our first Northern YSJournal conference, we have four main speakers/workshops to enjoy throughout the day. First is the Kitchen Chemistry workshop with Dr Stephen Ashworth, who aside from being a full time lecturer at UAE travels around the country presenting awesome science shows. A strong believer in science being a practical experience, we are […]

Suspending a dipole radar scanner from a helicopter – improving methods of evaluating glacial water resources

Posted on

Suspending a dipole radar scanner from a helicopter – improving methods of evaluating glacial water resources   Abstract    Glaciers cover about 10% of the Earth’s surface and water from melted glaciers is important for local people to drink and to irrigate their land, as well as for hydroelectric power. Understanding the thickness and change […]

DO YOU WANT TO TRAVEL IN SPACE? ASK KATHERINE! During the Cold War, the two greatest world powers, USA and URSS, tried to dominate especially when it came to their own scientific achievements. URSS managed to launch the Sputnik in 1957, accomplishing the wider part of their space program at the same time. Simultaneously NACA, […]

Photovoltaic Cells

Posted on

Photovoltaic Cells Photovoltaic cells are a type of semiconductor diode which generates direct current from visible light. This article will briefly explore the origination of photovoltaics, how photovoltaic cells work, disadvantages and advantages, and their application in the real word. Whilst the hydrogen atoms in the Sun fuse to form helium, gamma photons and neutrinos […]

Violin Harmonics 的图像结果

Abstract This report presents the results of research into artificial harmonics on the violin. In the first experiment, the ratio of string lengths between fingers was measured to determine their effect on the pitch of the artificial harmonic. The results of the first experiment indicated that the fourth finger was always placed a quarter of […]

Exploring the Realm of Conductivity

Posted on

Abstract This article explains the different types of conductors, their function, and delves into the way they conduct. It explores how and why they work, what material they are made of, and what could be their future applications. It also discusses the quantum aspects of conduction, which is explained through a classical point of view. […]

NASA’s Exoplanet Discovery – Trappist-1

Posted on

Seven earth-sized planets have been discovered recently by NASA, in the constellation of Aquarius. The exoplanet (a planet that orbits a star other than our Sun) system is called TRAPPIST-1, which stands for The Transiting Planets and Planetesimals Small Telescope. The tiny, dim star the planets are orbiting is only about 40 light-years (235 trillion […]

King’s Hub: Videos You Should Watch

Posted on

Here is a selection of short, fun and interesting videos recommended by the King’s Hub. There is something for every scientist, with maths, physics, biology and chemistry related content. Although they are great to watch purely as entertainment, the King’s Hub also loves these videos because they show the wonderful (and slightly weird) knowledge that science […]

Magnesium diboride superconducting cables! A new superconducting prototype cable has been developed to aim to create superconducting transmission lines for improved efficiency and less of an environmental impact for the electricity grid. To meet future energy demands, all the electricity grids throughout Europe will need to be upgraded and expanded for higher transmission capacity. For […]

Carbyne: Officially the strongest material in the world

Posted on

Scientists in Vienna have successfully created a stable form of carbyne, the world’s strongest material. Carbyne is a linear acetylenic carbon – an infinitely long carbon chain. It can be considered as a one-dimensional allotrope of carbon. Carbyne has a chemical structure with alternating single and triple bonds: (−C≡C−)n. This structure of carbon gives an […]

Jim Al-Khalili Interview

Posted on

Young Scientists Journal was fortunate to interview Jim Al-Khalili, a prominent science communicator and Professor of Theoretical Physics at the University of Surrey. Laura Patterson, from the King’s School YSJournal hub, went down to Surrey to talk to him about his work in physics and science communication. Jim has presented several science documentaries and radio […]

On the Relation of Entropy with Gravity

Posted on

This paper hypothesizes a connection between gravity and entropy. Gravity, which has not been successfully unified with other fundamental forces yet, is now alternatively explained as an entropic force that is caused by change in information associated with the positions of material bodies. We consider the statistical definition of entropy and ultimately conclude that gravity and entropy are two sides of the same coin and their inter-conversion is what we call ‘time’.
