ABSTRACT: Science and the technologies it has spawned have been the principal drivers of the American economy since the end of World War II. Today, economists estimate that a whopping 85 percent of gross domestic product (GDP) growth traces its origin to science and technology. The size of the impact should not be a surprise, considering the ubiquity of modern technologies.

Innovation has brought us the consumer products we take for granted: smart phones and tablets, CD and DVD players, cars that are loaded with electronics and GPS navigating tools and that rarely break down, search engines like Google and Yahoo, the Internet and the Web, money-saving LED lights, microwave ovens and much more. Technology has also made our military stronger and kept our nation safer. It has made food more affordable and plentiful. It has provided medical diagnostic tools, such as MRIs, CT scanners and genomic tests; treatments for disease and illness, such as antibiotics, chemo-therapy, immunotherapy and radiation; minimally-invasive procedures, such as laparoscopy, coronary stent insertion and video-assisted thoracoscopy; and artificial joint and heart valve replacements.

None of those technological developments were birthed miraculously. They owe a significant part of their realization to public and private strategies and public and private investments. Collectively the strategies and investments form the kernel of science and technology policy. Navigating the Maze is a narrative covering more than 230 years of American science and technology history. It contains stories with many unexpected twists and turns, illustrating how we got to where we are today and how we can shape the world of tomorrow.

ABOUT THE SPEAKER

Michael Lubell is the Mark W. Zemansky Professor of Physics at the City College of the City University of New York (CCNY). He has spent much of his career carrying out research in high-energy, nuclear and atomic physics, as well as quantum optics and quantum chaos, and is an elected fellow of the American Association for the Advancement of Science and the American Physical Society He is well known in public policy circles for his ground-breaking work in Washington, DC, where he served as director of public affairs of the American Physical Society for more than two decades. He has published more than 300 articles and abstracts in scientific journals and books and has been a newspaper columnist and opinion contributor for many years. He has been active in local, state and national politics for half a century and has lectured widely in the United States and Europe. Navigating the Maze is his first full-length book.

ABSTRACT: In this talk, I will discuss the optical biopsy (OB) techniques we have used for cancer diagnosis. Currently the gold-standard method for cancer diagnosis is needle biopsy along with histopathology. This process is invasive, time consuming, and subjective due to the judgment of pathologists. OB is a collection of alternative optical spectroscopy and imaging techniques that are used as diagnostic tools and have attracted enormous attention in the past decades. Native fluorescence spectroscopy (NFS) and Raman spectroscopy (RS) are two important OB techniques which can detect biochemical and morphological information in biological samples at the molecular level based on the excitation, emission, or vibrational properties of the molecules. Such techniques are label free and non-invasive, and can operate rapidly in vivo. We have used these techniques to diagnose different types of cancer, distinguish normal and cancerous tissues, identify cancer grades, detect metastatic ability of cancer cells, etc. 
In particular, I will discuss a new Raman technique, visible resonance Raman (VRR) using 532nm for excitation. Most Raman-based cancer studies in the literature have used near-infrared (NIR) laser excitation, where Raman signal is very weak. Using high power (e.g. 300mW) or long exposure time (e.g. minutes) led to limitation of the technique for practical applications. In contrast, due to the resonance effect, VRR was shown to provide enhanced Raman peaks for key biomolecules which may be used as markers for cancer diagnosis. 
In the meantime, I will discuss the application of artificial intelligence (AI) in the research. Often times, analyzing spectral or imaging data from biological samples is challenging due to the complexity of the data. Machine learning (ML) or deep learning (DL) for AI has been shown to be a promising approach to analyze the “big” data. AI can detect salient features from the high-dimension spectral data, reveal biochemical and morphological information, for accurate diagnosis and prognosis of cells/tissue. 
Optical biopsy with AI techniques brings great opportunities to the field of healthcare. In particular, it provides promising novel techniques for accurate, noninvasive, early detection of cancers.

ABSTRACT: We are now experiencing a revolution in optical technologies: in the past the state of the art in the field of photonics transitioned from individual miniaturized optical devices to massive optical circuits on a microelectronic chip that can be modified on demand. This revolution is ongoing –new materials and technologies are emerging to control the flow of light in unprecedented ways and it is opening the door to applications that only a decade ago were unimaginable.

ABSTRACT:

The physical laws are very special: they allow not only for life to appear and develop, but to develop up to high forms compatible with thinking about nature and about thinking itself. Following conventional terminology, this remarkable feature of the laws may be called anthropness. The laws are even more special though: being sufficiently rich in  complicated solutions for the anthropness, they are, at the same time, sufficiently simple and elegant to be discoverable by these very anthropoi. They are also universal, very precise and in a sense complete. A universe with such laws, both complicated and simple, may be called Pythagorean, in honor of the great ancient thinker who first somehow foresaw this. Why are the laws both anthropic and discoverable, making our universe Pythagorean? What answers have been suggested so far? Is there at least one that is reasonable?

Speaker: Alexey Burov was born and raised in Novosibirsk, USSR. He defended his PhD in theoretical and mathematical physics at Budker Institute of Nuclear Physics, Novosibirsk, and his main expertise relates to charged particle beams. Since 1997 he has been working at Fermi National Accelerator Laboratory (Fermilab). He worked at CERN during its Run I, when the Higgs boson was discovered. Alexey is an author of many journal publications on beam optics, cooling, diffusion and instabilities; he is a Fellow of American Physical Society. Apart from physics, he also authored numerous philosophical essays, in Russian and in English, many of them together with his son Lev. Their treatise “Genesis of a Pythagorean Universe” received an award from the Foundational Questions Institute, FQXi.org. Since 2013, Alexey authors a philosophical blog (in Russian, at snob.ru), and chairs the philosophy society at Fermilab (in English), which he founded. Many of his philosophical compositions are published in major Russian literary magazines.
