The infamous assertion made by the ancient Greek polymath is […]
Glenn Borchardt: 10 Assumptions of Science
In his book “The Ten Assumptions of Science: Toward a New Scientific Worldview,” Dr. Glenn Borchardt presented a set of assumptions he deemed would define 21st-century scientific philosophy. He specifically argued that assumptions and not absolutes are necessary for scientific thinking. Furthermore, he noted how critical choices among underlying assumptions either clarify or muddle scientific […]
Pros and Cons of Carbon Capture and Storage
The entire process of carbon capture and storage or CCS involves capturing carbon dioxide from point sources, processing and transporting the captured CO2 for storage, and storing or disposing them to a final location selected and in most cases, reinforced to prevent the captured CO2 from entering the atmosphere. The process has been positioned as […]
