Chick embryos are used for studying human glioblastoma (GBM) brain tumors in ovo and in ex vivo brain slice co-cultures. GBM cell behavior can be recorded by time-lapse microscopy in ex vivo co-cultures, and both preparations can be analyzed at the experimental endpoint by detailed 3D confocal analysis.

Scientific Method - Concepts
0 Views •
2019
The scientific method is used to solve problems and explain phenomena. The development of the scientific method coincided with changes in philosophy underpinning scientific discovery, radically transforming the views of society about nature. During the European Renaissance, individuals such as Francis Bacon, Galileo, and Isaac Newton formalized the concept of the scientific method and put it into practice. Although the scientific method has been revised since its early conceptions, much of the...

Inclined planes let Galileo investigate motion under conditions that were easier to observe and measure than direct free fall. By studying bodies moving along a slope, he could identify regular patterns and express them mathematically. This approach shifted mechanics away from inherited claims about motion and toward controlled experiments linked to quantitative descriptions.
Measurement allowed Galileo to compare observed motion with mathematical relationships rather than relying only on philosophical arguments. His work showed that repeated observations could reveal regularities in falling bodies and other forms of motion. That connection between measured evidence and mathematical description became a central principle of experimental physics.
Galileo’s analysis of motion contributed to the foundations of inertia, the idea that motion can persist rather than requiring continuous explanation through inherited concepts. Although his work did not complete the later formulation of mechanics, it changed how physicists approached motion. This conceptual shift helped establish experimental mechanics as a field grounded in observable behavior.
Galileo used telescopic observations to examine the Moon, Jupiter’s moons, and Venus. These observations showed that celestial bodies could move around something other than Earth and provided evidence against the view that Earth was the center of every celestial motion. They therefore strengthened the case for a Sun-centered model through direct astronomical evidence.
Galileo combined controlled experimental conditions with mathematical models, creating a procedure for turning physical observations into testable descriptions. This approach could be applied to motion and falling bodies rather than remaining limited to abstract debate. Its lasting value lies in connecting evidence, measurement, and theory, which remains central to how physics investigates natural regularities.
A focused study should examine both his mechanical experiments and his telescopic evidence. Inclined-plane work illustrates how controlled measurements can clarify motion, while observations of the Moon, Jupiter’s moons, and Venus show how instruments can test assumptions about the cosmos. Together, these examples connect experimental mechanics with broader changes in physical and astronomical thinking.
