The ancient Romans had many public flush bathrooms, which emptied into an intensive sewage system. The main sewer in Rome was the Cloaca Maxima; construction started on it in the sixth century BCE and it's still in use at present. Hominids started using primitive stone tools hundreds of thousands of years in the past. The earliest stone instruments have been little more than a fractured rock, but approximately 75,000 years in the past, strain flaking provided a approach to make much finer work. The distinction between science, engineering, and technology is not at all times clear. Science is systematic knowledge of the physical or materials world gained via observation and experimentation.
Robert Gilliard, an MLK Visiting Professor and Scholar, is working with chemistry professor Christopher Cummins to synthesize new chemical molecules from the edges of the periodic desk, whereas prioritizing collaboration and pupil mentorship. Spoiler Alert, a startup aimed toward decreasing food waste, has saved over 200 million pounds of food. “One of our core beliefs is that waste is now not a needed or acceptable price of doing enterprise,” cofounder Emily Malina ’13 advised the Boston Globe.

More just lately, trendy works of science fiction similar to those by Philip K. Dick and William Gibson and movies such as Blade Runner and Ghost in the Shell project extremely ambivalent or cautionary attitudes toward technology's impression on human society and identity. Scientific advances and the discovery of new ideas later allowed for powered flight and developments in medication, chemistry, physics, and engineering. The rise in technology has led to skyscrapers and broad urban areas whose inhabitants rely on motors to transport them and their meals provides. Communication improved with the invention of the telegraph, telephone, radio and tv. The late-19th and early-20th centuries saw a revolution in transportation with the invention of the airplane and vehicle.
