Figure 1. Photograph of Inge Lehmann beside a scan of her original diagram showing discovery of the Earth’s inner core (Lehmann, 1936). For improved clarity, the circles representing the inner core and the fluid core have subsequently been traced over in red and purple, respectively. The shadow zone, not specifically marked on her original diagram, is indicated in blue. Note the reflection of ray #5 into the shadow zone.

Time-Travel for Science Revolutions: Inseparability of Science History and Discovery

A recurrent theme of science fiction is to travel backward in time to change the present by correcting errors or events in the past. While physical time-travel is impossible, through an understanding of science history, one can progress backward in time, in a manner of speaking, to discover, and...

Persistent Geo-Blunder Discovered: Huge Boost for Oil and Gas Exploration

SAN DIEGO, March 23, 2010 – For decades, an unsuspected geological blunder has limited crucial technical understanding of how, where and why petroleum and natural gas deposits form. Exposing and correcting that vital mistake offers the promise of new insights and potentially vast new...

American Governance: Allowing Taxpayers to Decide How Their Own Tax Payments Should Be Spent

From a pragmatic standpoint, the proposal I am making could be phased in gradually and would be voluntary. Those so choosing would be able to participate directly to the extent of their tax payments and thus exercise a new level of civic responsibility.

Corruption of Science in America

The purpose of science is to discover the true nature of Earth and Universe and convey that knowledge truthfully to people everywhere. Beneath the surface lies a system which has been corrupted and evolved to support a ‘politically correct’ consensus ¬view, while stifling challenges by individuals.

Peer Review Folly: Independent Critique and Recommendations

Can a major government self-appraisal really be objective? One independent scientist’s critique shows what’s wrong with peer review and how to fix it. But does anyone pay attention?
