Do objects have weight in space? - Take your classroom into space

submitted by: cristina
What's the difference between mass and weight? Do objects have weight in space? Students using ESAs 'Take Your Classroom into Space' kit and this video recorded in the unique environment of the ISS can now find out. The experiment was proposed by Greek, Belgian and Spanish teachers who participated to the ESA competition 'Take Your Classroom into Space'.

Three Biggest Mistakes in Science, Part 3/3 - Inverse Square Law of Gravity

submitted by: kmarasakatla

Our understanding of fundamental concepts like force, definition of mass and the inverse square law of gravity appears to be flawed. Our entire underdstanding of science is dependent on these very basic concepts. This three part series explores the validity of these concepts.
