StarGates: Theory and Practice

•

0 likes•243 views

Call them Stargates, Jumpgates, Fargates, Hypergates or just an invitation to every unwanted pest from the far reaches of the Galaxy to visit, they're absolutely necessary if we're to have the glorious Science Fiction action we desperately need. Could they actually be built? Modern physics may permit: how to glue black holes together to build a wormhole, how to avoid the dangers of spaghettification, radiation poisoning and paradox noise, and just what would it take to build one in practice.

Star Gates: the Theory and Practice

John Ashmead

Call them Stargates, Jumpgates, Fargates, Hypertubes or just an invitation to every unwanted pest from the far reaches of the Galaxy to visit, they are absolutely necessary if we are to have the glorious Science Fiction action we desperately need. But could they actually be built? We look at what modern physics has to say: how to glue black holes together to build a wormhole, how to avoid the dangers of spaghettification, radiation poisoning, and paradox noise, and just what it would take to build one in practice.

Time dispersion in quantum mechanics

John Ashmead

Is time fuzzy? In quantum mechanics space is fuzzy. And in special relativity time and space are interchangeable. But if time and space are interchangeable, shouldnt time be fuzzy as well? Shouldnt quantum mechanics apply -- to time? Thanks to recent technical advances we can put this to the test. We ask: How do you get a clock in a box? How do you interfere with time? When is one slit better than two? And what happens at the intersection of time and quantum mechanics?

What are the advantages of the quantum internet? key problems? Who will get to use it? And do we have just a bunch of interesting technologies that all have quantum in their name or can the whole be more than the sum of its parts?

Time dispersion in quantum mechanics -- Philcon 2019 version

John Ashmead

We know from quantum mechanics that space is fuzzy, that particles don’t have a well-defined position in space. And we know from special relativity that time and space are interchangeable. But if they are interchangeable, shouldn’t time be fuzzy as well? Shouldn’t the rules of quantum mechanics apply — along the time dimension? Bohr and Einstein — who disagreed on so much — nevertheless agreed on this.

Practical Telepathy: The Science & Engineering of Mind-Reading

John Ashmead

The document discusses the history and future of telepathy and mind reading. It covers early concepts of mentalism and ESP, scientific studies by Rhine and modern brain imaging techniques like fMRI. The document also discusses emerging technologies that could enable two-way mind-to-mind communication through brain interfaces and issues around privacy and control of one's thoughts. It presents both opportunities like helping disabled people and risks of not fully understanding the complex human mind.

From Startup to Mature Company: PostgreSQL Tips and techniques

John Ashmead

This talk is for people relatively new to PostgreSQL who are wondering: How do I get going with PostgreSQL -- in a way that won’t create problems later on! We’ll go over best practice in: Table design Indexing PostgreSQL types Stored procedures -- when & how to use, when not Triggers How to work with a web framework (i.e. Ruby-on-Rails): what works belongs in the framework, what should be done in the database Error & exception management Doing the right amount of planning Why you might want to build the help system first, and use it to help build the rest. Nistica has its ownership in Japan, engineering in New Jersey, & manufacturing in Vietnam so we’ll take a special look at: Handling different languages & character sets Timestamps & time zones How to sync data from one part of the world to another without letting data fall on the floor or creating infinite loopiness. Nistica has gone from startup to world player in the manufacture of optical switches. It has run its manufacturing on PostgreSQL from the start, using PostgreSQL to drive every step from assembly to quality assurance & tracking all part data in the database. Going from the ad hoc procedures appropriate for a startup to the disciplined approaches required by the world market has taught us a lot about how to get the best out of PostgreSQL. We’ve learned a lot from the PostgreSQL community; now we’d like to share some of what we’ve learned from our experience.

Practical Telepathy: The Science & Engineering of Mind-Reading

John Ashmead

From van Vogt's Slan to Willis's Crosstalk, telepathy has been a staple of science fiction. But what are the real world chances of reading another person's mind? With MRI & PET scans we can see what images a person is thinking of, with brain implants we can help the blind to see, and -- the way the science is going -- we are only a half-step away from direct mind-to-mind communication. Nothing to worry about here!

Seven War Stories and a Moral

John Ashmead

The document describes 7 stories from the author's career as a programmer. Each story highlights a different challenge solved through creative technical solutions: 1) Automating stored procedure generation. 2) Generating joins by reading metadata. 3) Mapping fonts to work around software limitations. 4) Creating an easy-to-use program for a coworker with disabilities. 5) Writing a file checking utility in a day. 6) Creating a color-coded report to identify issues across departments. 7) Monitoring remote switches and troubleshooting connection issues. The last story describes consolidating duplicate reports into a single automated report. The moral is to know the technology, business needs, and take time for creative thinking.

MAMP Stack - Macintosh, Apache, MySQL, PHP

John Ashmead

This document discusses MAMP (Macintosh, Apache, MySQL, PHP), a free and open-source web development environment for macOS. It provides an overview of MAMP itself as a German company and its generally stable but sometimes finicky releases. Key components like the Apache web server, MySQL database, and PHP programming language are explained. The benefits of developing websites locally before deploying and tools like PhpMyAdmin for database administration are also summarized.

Automation

John Ashmead

"It is a profoundly erroneous truism, repeated by all copybooks and by eminent people making speeches, that we should cultivate the habit of thinking of what we are doing. The precise opposite is the case. Civilization advances by extending the number of important operations we can perform without thinking about them. Operations of thought are like cavalry charges in a battle - they are strictly limited in number, they require fresh horses, and must only be made at decisive moments." -- Alfred North Whitehead,

Applied Science: Thermodynamics, Laws & Methodology.pdf

University of Hertfordshire

When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best. Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level. Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Nucleophilic Addition of carbonyl compounds.pptx

SSR02

Nucleophilic addition is the most important reaction of carbonyls. Not just aldehydes and ketones, but also carboxylic acid derivatives in general. Carbonyls undergo addition reactions with a large range of nucleophiles. Comparing the relative basicity of the nucleophile and the product is extremely helpful in determining how reversible the addition reaction is. Reactions with Grignards and hydrides are irreversible. Reactions with weak bases like halides and carboxylates generally don’t happen. Electronic effects (inductive effects, electron donation) have a large impact on reactivity. Large groups adjacent to the carbonyl will slow the rate of reaction. Neutral nucleophiles can also add to carbonyls, although their additions are generally slower and more reversible. Acid catalysis is sometimes employed to increase the rate of addition.

Phenomics assisted breeding in crop improvement

IshaGoswami9

As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus, high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology, and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
