John G. Lindberg
John Gustaf Lindberg (22 June 1884 – 23 November 1973) was a Finnish ophthalmologist who was the first to describe exfoliation syndrome, an age-related degenerative disease of the eye that often complicates glaucoma and cataract surgery, in his doctoral thesis that he wrote in St. Petersburg and defended in March 1917 in Helsinki, Finland, at that time a Grand Duchy in the Russian Empire. Early years John Gustaf Lindberg was born to Gustaf Robert Lindberg (1844–1929), a Finnish engineer working in St. Petersburg, Russia, as a department manager in St. Petersburg Metalworks supervising the construction of boilers for steam engines and of metal bridges, and Anna Heloise Rautelin. Lindberg was the second of three boys in the family. St. Petersburg thus became his home town, a fact that was to influence his career. The family moved to Helsinki, Grand Duchy of Finland in the early 1890s after his father had been offered a position as the Director of Technology in a recen ...

Russian Empire
The Russian Empire was an empire and the final period of the Russian monarchy from 1721 to 1917, ruling across large parts of Eurasia. It succeeded the Tsardom of Russia following the Treaty of Nystad, which ended the Great Northern War. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing China. It also held colonies in North America between 1799 and 1867. Covering an area of approximately , it remains the third-largest empire in history, surpassed only by the British Empire and the Mongol Empire; it ruled over a population of 125.6 million people per the 1897 Russian census, which was the only census carried out during the entire imperial period. Owing to its geographic extent across three continents at its peak, it featured great ethnic, linguistic, religious, and economic diversity. From the 10th–17th centuries, the land ...

Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Medical Degree
A medical degree is a professional degree admitted to those who have passed coursework in the fields of medicine and/or surgery from an accredited medical school. Obtaining a degree in medicine allows for the recipient to continue on into specialty training with the end goal of securing a license to practice within their respective jurisdiction. Medical graduates may also pursue non-clinical careers including those in basic research and positions within the healthcare industry. A worldwide study conducted in 2011 indicated on average: 64 university exams, 130 series exams, and 174 assignments are completed over the course of 5.5 years. As a baseline, students need greater than an 85% in prerequisite courses to enroll for the aptitude test in these degree programs. Undergraduate medical degrees * Bachelor of Medicine, Bachelor of Surgery (MBBS, BMBS, MBChB, MBBCh) * Bachelor of Medicine (B.Med, MB, BM) * Bachelor of Surgery (B.S)/(B.Surg) The MBBS is also awarded at the graduate l ...

Medical School
A medical school is a tertiary educational institution, or part of such an institution, that teaches medicine, and awards a professional degree for physicians. Such medical degrees include the Bachelor of Medicine, Bachelor of Surgery (MBBS, MBChB, MBBCh, BMBS), Master of Medicine (MM, MMed), Doctor of Medicine (MD), or Doctor of Osteopathic Medicine (DO). Many medical schools offer additional degrees, such as a Doctor of Philosophy (PhD), master's degree (MSc) or other post-secondary education. Medical schools can also carry out medical research and operate teaching hospitals. Around the world, criteria, structure, teaching methodology, and nature of medical programs offered at medical schools vary considerably. Medical schools are often highly competitive, using standardized entrance examinations, as well as grade point averages and leadership roles, to narrow the selection criteria for candidates. In most countries, the study of medicine is completed as an undergraduate de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemistry
Chemistry is the science, scientific study of the properties and behavior of matter. It is a natural science that covers the Chemical element, elements that make up matter to the chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a Chemical reaction, reaction with other Chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties ...

Physics
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physic ...

Zoology
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the Animal, animal kingdom, including the anatomy, structure, embryology, evolution, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botany
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning " pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – ed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
