Factory of the Future?
Factory of the Future? Microsoft alum Nathan Myhrvold runs a firm that doesn't make anything, but it's hoarding the key to a new business age: intellectual property By Brad Stone Newsweek Nov. 22, 2004 issue - The offices of the highly secretive Seattle-area start-up, Intellectual Ventures, are filled with evidence of the multiple hobbies of its polymath founder, Nathan Myhrvold. The multimillionaire former chief technologist at Microsoft is a scientist, so there's a collection of antique microscopes in his office. He is a photographer, so striking pictures of nature adorn all the walls. He is an avid writer, so antique typewriters line the hallway. And since he is also a paleontologist, the full-scale head of a T. rex lords it over the lobby. It's actually a replica of the model used in the second "Jurassic Park" Robbie McClaran for Newsweek film. 'Wild and crazy' guy: Myhrvold The dino's ferociously bared teeth hint at elements of Intellectual Ventures' bold business plan. Myhrvold and his partner, former Microsoft chief software architect Edward Jung, have created the quintessential company for the 21st century. It doesn't actually make anything: it outsources, offshores and offloads nearly every task performed by regular corporations. It has no factories, machine shops or marketing teams. Only patent attorneys populate the quiet hallways. The five-year-old firm's plan is to create or buy new ideas, accumulate patents—exclusive rights to use the inventions—and rent those ideas to companies that need them to do the gritty work of producing real products. -

Contents:- • Background to the philosophical approach • Some L.E.M . and climate model results • Technological issues. • Future plans and publications. Science Objectives:- • To explain the science of how stratocumulus clouds can have a significant effect on the earth’s radiation balance • To present some modelling results from Latham et al 2011 Marine Cloud Brightening, WRCP October 2011 1 Stratocumulus clouds cover more than 30% of ocean surface Stratocumulus clouds have a high reflectance, which depends on droplet number and mean droplet size. Twomey Effect .:- Smaller drops produce whiter clouds . Proposal :- To advertently to enhance the droplet concentration N in low-level maritime stratocumulus clouds, so increasing cloud albedo (Twomey, JAS, 1977 ) and longevity ( Albrecht, Science, 1989 ) Technique:- To disseminate sea-water droplets of diameter about 1um at the ocean surface. Some of these ascend via turbulence to cloud-base where they are activated to form cloud droplets, thereby enhancing cloud droplet number concentration, N (Latham, Nature 1990 ; Phil Trans Roy Soc 2008 and 2011, under review ) 2 Above:- Computed spherical albedo for increasing pollution in THIN, MEDIUM and THICK clouds.

Some Facts of High-Tech Patenting
Some Facts of High-Tech Patenting Michael Webb Nick Short Nicholas Bloom Josh Lerner Working Paper 19-014 Some Facts of High-Tech Patenting Michael Webb Nick Short Stanford University Harvard Kennedy School Nicholas Bloom Josh Lerner Stanford University Harvard Business School Working Paper 19-014 Copyright © 2018 by Michael Webb, Nick Short, Nicholas Bloom, and Josh Lerner Working papers are in draft form. This working paper is distributed for purposes of comment and discussion only. It may not be reproduced without permission of the copyright holder. Copies of working papers are available from the author. Some Facts of High-Tech Patenting Michael Webb, Nick Short, Nicholas Bloom, and Josh Lerner NBER Working Paper No. 24793 July 2018 JEL No. L86,O34 ABSTRACT Patenting in software, cloud computing, and artificial intelligence has grown rapidly in recent years. Such patents are acquired primarily by large US technology firms such as IBM, Microsoft, Google, and HP, as well as by Japanese multinationals such as Sony, Canon, and Fujitsu. Chinese patenting in the US is small but growing rapidly, and world-leading for drone technology. Patenting in machine learning has seen exponential growth since 2010, although patenting in neural networks saw a strong burst of activity in the 1990s that has only recently been surpassed. In all technological fields, the number of patents per inventor has declined near-monotonically, except for large increases in inventor productivity in software and semiconductors in the late 1990s. In most high-tech fields, Japan is the only country outside the US with significant US patenting activity; however, whereas Japan played an important role in the burst of neural network patenting in the 1990s, it has not been involved in the current acceleration. -

Young Scientists
Young Scientists Applied mathematics Erez Aiden is an Assistant Professor in the Department of Genetics at the Baylor College of Medicine, where he directs the Center for Genome Architecture, and in the Department of Computer Science and Computational and Applied Mathematics at Rice University. His research has made fundamental contributions to a large variety of disciplines, including molecular biology, polymer physics, historical linguistics, wearable computing, and mathematics. These include: development of a three-dimensional genome sequencing method; discovery of dynamic reorganization of the genomic architecture to facilitate gene expression or silencing; the characterization of the genome as a “fractal globule;” quantitative analysis of the evolutionary dynamics of language which led to the discovery that the rate of verb regularization depends on the inverse-square of its usage frequency. He has over 20 patents in various stages of filing. Co- inventors include Bob Langer, Nathan Myhrvold and Bill Gates. Microfluidic methods Adam Abate is Assistant Professor in Bioengineering at the School of Pharmacy of the University of California at San Francisco. He is a physicist whose research employs microfluidics for high-throughput biological applications. He has developed microfluidic methods to create emulsions that consist of droplets of very precise and consistent sizes that are used to create micro-compartments, which can be loaded with single cells and other active materials, such as drugs, nutrients, and assay reagents. The droplets can be used as tiny “test tubes” for performing chemical and biological reactions. This approach is used for directed evolution, genetic sequencing and cell sorting. Optical sensors Andrea Armani is the Fluor Early Career Chair in Engineering and Associate Professor of Chemical Engineering and Materials Science at the University of Southern California. -

She had been pondering the craters left by comets and asteroids that smashed into Earth. Geologists had counted them and concluded that space strikes are rare events and had occurred mainly during the era of primordial mists. But, Abbott realized, this deduction was based on the number of craters found on land—and because 70 percent of Earth’s surface is water, wouldn’t most space objects hit the sea? So she began searching for underwater craters caused by impacts VIDEO: "TARGET EARTH" rather than by other forces, such as volcanoes. What she has found is spine-chilling: evidence Gregg Easterbrook leads an illustrated that several enormous asteroids or comets have slammed into our planet quite recently, in tour through the treacherous world of space rocks. geologic terms. If Abbott is right, then you may be here today, reading this magazine, only because by sheer chance those objects struck the ocean rather than land. Abbott believes that a space object about 300 meters in diameter hit the Gulf of Carpentaria, north of Australia, in 536 A.D.
