Marie Curie
Marie Curie's work in radioactivity changed the way scientists think about matter and energy and led to advancements in the treatment of disease. With her fellow scientist and husband, Pierre Curie, she searched for the source of radioactivity and discovered two elements, radium and polonium. They shared the 1903 Nobel Prize, the world's highest science award, for their discovery.
Seeking a Better Future
Most emigration from England was voluntary, self-financed, and pursued by people who, while expecting to improve their economic prospects, were also critical of the areas in which they first settled. The exodus from England that gathered pace during the 19th century accounted for the greatest part of the total emigration from Britain to Canada. And yet, while copious emigration studies have been undertaken on the Scots and the Irish, very little has been written about the English in Canada. Drawing on wide-ranging data collected from English record offices and Canadian archives, Lucille Campey considers why people left England and traces their destinations in Ontario and Quebec. A mass of detailed information relating to pioneer settlements and ship crossings has been distilled to provide new insights on how, why, and when Ontario and Quebec acquired their English settlers. Challenging the widely held assumption that emigration was primarily a flight from poverty, Campey reveals how the ambitious and resourceful English were strongly attracted by the greater freedoms and better livelihoods that could be achieved by relocating to Canada’s central provinces.
Pioneers in Cell Biology
Introduces some of the most influential scientists in the history of cell biology.
Thomas Edison and the Pioneers of Electromagnetism
Thomas Edison's inventions changed the world. His most famous invention is the light bulb, but he also invented generators and the power grid. Edison holds 1,000 patents-the record for the most new inventions. He even started his own electric company.
Investigating the Chemistry of Atoms
Atoms are the building blocks of everything around us. Inside the atom is the nucleus, with protons and neutrons. But there are even smaller particles that make up protons and neutrons, called quarks. Everything that scientists know about atoms is part of the Atomic Theory, which originated in ancient Greece, but continues even today.
Pioneers in Cell Biology
Anton van Leeuwenhoek was not educated in science, but he created the best microscopes of the 17th century. He made more than 400 microscopes and used them to study living organisms. British scientist Robert Hooke was the first scientist to observe cells and give them their name. Many scientists are still making discoveries in the areas of genetics and stem cell research.
Investigating Electromagnetism
Electromagnetism is the combined power of electricity and magnetism. Almost everything we do-from watching television to using a computer-is affected by electromagnets. In the 1830s, scientist Michael Faraday proved that electricity and magnetism are different ways to observe a unified force that he called electromagnetism.
