“I wanted to find answers to fundamental questions, and I wanted to know what holds the world together. Minimal electrical voltage is used to slip a single atom between a silver and a platinum pad, causing a digital signal to be emitted. To begin its work, the Centre of Atomic Scale Technologies is using initial Foundation funding to create 14 positions for PhD candidates and postdocs, and to purchase additional equipment to analyse and optimise nano-components. Hubble’s discovery was the first observational support for Georges Lemaître’s Big Bang theory of the universe, proposed in 1927. Lemaître proposed that the universe expanded explosively from an extremely dense and hot state, and continues to expand today. Subsequent calculations have dated this Big Bang to approximately 13.7 billion years ago.
- PSI in Villigen is a much sought-after place for scientists dedicated to researching the pion.
- The new chip will be 100 times smaller

Now researchers at ETH have found a way to apply this measurement principle to individual atoms. One can attach and detach single electron charges to molecules and atoms using the microscope tip . Using Kelvin probe force microscopy, we detect atomic charge states and molecular charge distributions . Imaging the structure of molecules with atomic resolution was achieved by noncontact atomic force microscopy (NC-AFM).
This workshop follows the submission of a community letter, which outlined the intention to organise a community workshop is to discuss options for a quantum technology development programme coordinated at the Europe-wide level. An even more mysterious form of energy called “dark energy” accounts for about 70% of the mass-energy content of the universe. This idea stems from the observation that all galaxies seems to be receding from each other at an accelerating pace, implying that some invisible extra energy is at work. Phillips, “Laser cooling … Read More
Particle physics probes the basic building blocks of matter and their interactions, which determine the structure and properties of the extreme diversity of matter in the universe. The web portal makes the fascinating research understandable to an interested public. To produce pionic helium, one of the two electrons of the helium atom is replaced by a pion. This artificially created atom can then be examined with a laser beam.
- For instance, when sending signals from a cell phone or a computer, the nano-components can be transformed into optical signals, which are reverted to their original form when received.
- Each pair of neighboring atoms oscillated like two masses linked by a spring, and this oscillation was synchronous across the entire illuminated region.
- By 2021, the researchers aim to have laid the theoretical and technological groundwork necessary to create a prototype processor with 20 single-atom components.
- But when superpositions do occur, they

After applying the microwave field for some time, its spatial field distribution is therefore imprinted onto the hyperfine state distribution in the atomic cloud. From this distribution, which we image onto a CCD-camera, we can reconstruct the microwave field. We strive to image and measure molecular properties with ever increasing resolution. We are investigating the fundamental properties of individual atoms and molecules on solid surfaces. We are specifically interested in the build-up of novel molecules and atomic-scale nanostructures using atom manipulation, that is, creating them with the tip of the microscope. Microwaves are an essential part of modern communication technology.

This science fair project idea enhances awareness of local food production and food sourcing. Provide pathway opportunities to learners and ensure that graduates qualifications are internationally recognized. Born and raised in Michigan, Sam spent her childhood dreaming of the mountains and vast deserts of the American West. As an adult, she moved to California to study at the University of San Diego. During that time, Sam began teaching wilderness skills and leading outdoor adventure trips throughout the Southwest. Teton Science Schools is a nonprofit educational organization with headquarters in Jackson Hole, Wyoming.
Research shows that existing educator shortages disproportionately impact students of color, students from low-income backgrounds, students with disabilities, and, often, rural communities. Education.com has assembled a vast collection of science fair project ideas written by science teachers, professional scientists, and educational consultants on popular science fair topics ranging from physics and chemistry to biology and even sociology. We … Read More
