Force carrier particles in QED, mediating interactions between fermions. They are represented as wavy lines in Feynman diagrams. Examples include photons.

A branch of physics that studies the interaction of light and matter at a quantum level, explaining phenomena like the emission and absorption of light by atoms. Feynman diagrams are used to simplify complex calculations in QED.

A model explaining the fundamental building blocks of matter and their interactions, based on quarks and leptons, and their interactions through forces mediated by bosons. Feynman diagrams are used to depict these interactions.

The theoretical concept proposed by Murray Gell-Mann, stating that hadrons (particles like protons and neutrons) are composed of smaller, fundamental particles called quarks. This concept revolutionized our understanding of the structure of matter.

A theoretical physicist known for his work in particle physics, particularly for proposing the quark model, which led to the 'Standard Model' of particle physics. He won the Nobel Prize in Physics in 1969.

A theoretical physicist renowned for his work in QED and his intuitive diagrams that revolutionized our understanding of particle interactions, often quoted as saying 'Nobody understands quantum mechanics'.

A fundamental law in physics that states different directions in particle interactions are indistinguishable.

A type of subatomic interaction responsible for radioactive decay.

Yang Chen-Ning's research focused on challenging and proving the law of conservation of parity was invalid for weak interactions. This led to the development of the Yang-Mills theory on elementary particles.

In 1957, Yang Chen-Ning and Tsung-Dao Lee were awarded the Nobel Prize in Physics for their groundbreaking work challenging the law of conservation of parity.

A theory that unified weak and electromagnetic interactions, and provided a framework for understanding the forces that govern the subatomic world.

A branch of mathematics dealing with self-similar patterns that repeat at different scales.

A Polish-born mathematician who revolutionized mathematics by discovering fractal geometry.

A set of complex numbers that generate a fractal pattern when plotted, known for its intricate and infinitely repeating shape.

Fractal geometry can be used to analyze data with complex and seemingly chaotic patterns.

Fractal geometry has a wide range of applications in fields like medicine, engineering, and cosmology.

Hematologist Ernest McCulloch made groundbreaking discoveries on stem cells which revolutionized cancer research.

McCulloch's research primarily focused on the formation and development of blood, both normal and malignant.

In 1963, with colleagues Till and Becker, McCulloch published groundbreaking findings on stem cell research.

McCulloch was recognized for his advancements in leukemia studies and his overall impact on cancer research.

McCulloch's work influenced the development of regenerative medicine, a field that focuses on repairing damaged tissues and organs.

James Till, a pioneer in stem cell research, made the crucial discovery that most bones contain unspecialized cells called adult stem cells, residing in the inner marrow, capable of developing into any blood cell.

Till and Ernest McCulloch's research focused on the radiation sensitivity of mouse bone marrow cells, leading to their groundbreaking discovery of stem cells.

Till's research interests later broadened beyond stem cells to include cancer treatment, research ethics, patient quality of life, and using the internet for patient advocacy and support.

Till's research on stem cells has had a significant impact on the understanding of cell growth and has paved the way for advancements in stem cell therapies.

Till's early work on stem cell discovery was done in collaboration with Ernest McCulloch, who is equally recognized for their joint contributions to the field.

A type of cell with the unique ability to self-renew (make copies of itself) and differentiate into various specialized cell types, like blood cells.

The ability to self-renew is important because it ensures a continuous supply of stem cells to replenish the body's tissues.

McCulloch and Till discovered stem cells by observing the growth of nodules in the spleens of irradiated mice. These nodules were made up of clones, meaning they originated from a single stem cell.

Each nodule in the spleen originated from a single stem cell, forming a colony of identical cells.

The discovery of stem cells, by McCulloch and Till, opened up new possibilities for treating diseases by potentially using stem cells to regenerate damaged tissues and organs.
