Scientific Verification of Vedic Knowledge
29:23 - 3 years ago
A vast number of statements and materials presented in the ancient Vedic literatures can be shown to agree with modern scientific findings and they also reveal a highly developed scientific content in these literatures. The great cultural wealth of this knowledge is highly relevant in the modern world. Techniques used to show this agreement include: - Marine Archaeology of underwater sites (such as Dvaraka) - Satellite imagery of the Indus-Sarasvata River system - Carbon and Thermoluminiscence Dating of archaeological artifacts - Scientific Verification of Scriptural statements - Linguistic analysis of scripts found on archaeological artifacts - A Study of cultural continuity in all these categories.

About the Lecture
Tools developed by Martin Wattenberg and his associate Fernanda Viégas, have changed the way people look at and use visualizations, by empowering and equipping users with the methodology needed to ask different questions. Wattenberg, whose background is in math and computer science, asks how the humanities have influenced the evolution of data visualization and then answers with several examples from his own work.Web Seer compares Google's "auto-suggest" feature in one-to-one, weighted comparisons such as "why doesn't he…" and "why doesn't she…" The resultant text image uses the size of arrows and words to reflect frequency, demonstrating how text can impart meaning.
Another Wattenberg/Viégas collaboration is Many Eyes, a social media tool and Web site that has "democratized" powerful visualization systems by putting them in the hands of general audiences. This tool lets users visualize data in numerous ways, from scatterplots and bar charts to tree maps and stack graphs.
Word Tree, a visualization technique that lets users pick a word or phrase from a data set, shows the different contexts in which it appears via a tree-like branching structure. Chimera takes care of the "boilerplate problem" by examining large collections of text, such as contracts, and pointing out identical phrases. Seeing results arranged in faux 3D "skyscrapers" clearly illustrates levels of recurrence. Although Word Tree andChimera are fundamentally repetition searches, they are important tools for semantic analysis: simple, but revealing.
The idea behind Phrase Net is to expose a text's underlying network; this visualization tool diagrams the relationships between different words used in a text. It uses a simple form of pattern matching to provide multiple views of the concepts contained a book, speech, or poem.
Another Wattenberg/ Viégas collaboration is Fleshmap, "an inquiry into human desire." The relationship between the body and its visual and verbal representation are explored in a series of artistic studies employing song lyrics and body imagery. Flickr Flow, Wattenberg explains, is an experiment whose materials are color and time. Software calculated the relative proportions of different colors seen in photos of Boston taken during each month of the year and plotted those colors on a wheel creating a "river of meaning."
Wattenberg addresses questions regarding the impact of race in personified visualizations, and his subjective motives in selecting particular data for analysis. He admits that his "hard drive is loaded with failed visualizations," but emphasizes that the visualization process should be one of trial and error. As for encouraging the development of visual literacy, Wattenberg concludes, "as visualization becomes part of the discourse and people realize, 'this is something that's powerful, it can help me make my case in life,' they'll learn… I'm hoping for education and good, old-fashioned human brain power."

The God Helmet
THE GOD HELMET
Todd Murphy, 2007
| The God Helmet is the popular name given to a laboratory apparatus more correctly called the "Koren Helmet", after Stanley Koren of Laurentian University's Neuroscience Department, who built it according to specifications provided by Dr. M.A. Persinger, director. The Koren Helmet applies complex (having an irregular shape) magnetic signals to the head of the person who is wearing it. The Koren Helmet is connected to a PC computer through a 'black box' which cycles the signals through four coils on each side of the head over the temporal lobes of the brain. The temporal lobes are the area of the brain many researchers feel is the source of spiritual and religious experiences. link | ||||||
| This illustration shows how the signal shifts from one coil to the next. This is a side view. There is also another set of coils working on the other side. The two coils at the top are no longer used. The sessions are done in an Acoustic Chamber - a completely silent room. A large part of the temporal lobes ongoing activity is dedicated to monitoring ambient sound. The temporal lobes are the source of religious and mystic experiences, so that silence helps a great deal in creating these experiences in the lab. | ||||||
| Used as a research tool to investigate the bran's role in religious and mystic experiences, the Koren Helmet has been given the name God Helmet. A few Journalists gave it this name when they learned that some people had visions of God while participating in Koren Helmet experiments. The name has stuck. I asked Dr. Persinger how many people had seen God using the Koren Helmet, and this is what he said in reply:
| ||||||
| There is much more to the God Helmet than just the Koren Helmet alone. There is also a computer program called complex, authored by Stanley Koren, which allows the computer to create the signals. These signals are derived from EEG traces that appear in certain parts of the brain. Just as the brain responds to chemicals with specific shapes, it also responds to magnetic signals with certain shapes. Because these signals are complex, irregular things, it takes a special computer program to produce them. A third component is the acoustic - completely silent - chamber where the sessions take place. The last component is the 'black box' which converts output from the computer into input for the Koren Helmet. This box (not shown) is a specialized DAC (digital-to-analog converter). It's the core of the technology. The rest of the components of the God helmet are quite common. |
The God Helmet is a misleading name. It give the impression that it can produce the experience of God. In fact, only one percent of the subjects had the experience. It also passes over the crucial role of sensory deprivation - above all, the completely silent environment provided for the subjects. In contrast to the one percent who saw God, 80% of the subjects felt a presence of some kind, but did not call it God. Of course, there were probably some subjects who experienced an appearance of God, but were shy about saying they had seen God in a laboratory. That kind of thing is not only intensely personal, but can also get you ridiculed. If you saw god, would you tell your story just as it happened if you thought you weren't going to be taken seriously? A lot of people assume that, just because someone wears a lab coat, they won't believe such a vision can happen, or that it's a sign of a mental illness. Nothing could be further from the truth in this laboratory, but how would these subjects know that? They had been told they would be participating in an experiment to study relaxation response, and the experimenters were very careful not to encourage such glamorous reports.

Stan Koren is third from the bottom on the left. The Koren Helmet uses a snowmobile helmet to hold the coils in place. |

God on the Brain
Rudi Affolter and Gwen Tighe have both experienced strong religious visions. He is an atheist; she a Christian. He thought he had died; she thought she had given birth to Jesus. Both have temporal lobe epilepsy.
Like other forms of epilepsy, the condition causes fitting but it is also associated with religious hallucinations. Research into why people like Rudi and Gwen saw what they did has opened up a whole field of brain science: neurotheology.
The connection between the temporal lobes of the brain and religious feeling has led one Canadian scientist to try stimulating them. (They are near your ears.) 80% of Dr Michael Persinger’s experimental subjects report that an artificial magnetic field focused on those brain areas gives them a feeling of ‘not being alone’. Some of them describe it as a religious sensation.
His work raises the prospect that we are programmed to believe in god, that faith is a mental ability humans have developed or been given. And temporal lobe epilepsy (TLE) could help unlock the mystery.
