Dave Jones hosts Shahriar Shahramian and the discussion is something else.

It’s a geekfest. Shahriar Shahramian from The Signal Path met up with Dave Jones of EEVblog and discussion is well worth some time. It’s broken up into three videos each with their own focus. 1. Youtube & Bell Labs 2. Science, Debunking & Education 3. about the millimeter wave electronics and 5th generation RF These two […]

GPS and time

What time is it? and Where am I? – two seemingly simple questions but just look what happens when you start to explore the depths of the questions. Mario Corchero is doing a talk on It’s time for datetime at PyCon coming up in May. “We will also speak about different standards of time, time […]

Buckaroo Banzai weird?

It’s cited as one of 366 Weird Movies. “Would a watermelon in the midst of a chase sequence not be, in its own organic way, emblematic of our entire misunderstood enterprise? At once totally logical and perfectly irrational?”–W.D. Richter, explaining why there is a watermelon inside the Banzai Institute … Any movie that successfully incorporates […]

Seek and ye shall find – that it’s a harder journey than you ever imagined.

Luboš Motl takes off on Nautilus’ disillusioned ex-physicist. “Bob Henderson wrote an autobiography for Nautil.Us” and that provided the ammunition for a rant on Life’s Journey that any college freshman with ambition should read carefully. This is a sketch of the “path towards the deep laws of the Universe” that I already had in mind […]

Tools and how they corrupt the mind. Programming languages, thinking, and doing

Keep in mind that it is the craftsman and not the tools that solve problems and create solutions and that tools are the product of craftsman, too. Tools not only enable and facilitate, they also communicate. They are one craftsman sharing ideas with another. How you can do something influences how you think about doing […]

Finally, Weather service upgrades from RTTY

Anthony Watts reports: NOAA/NWS to stop ‘yelling’ at the public in their forecasts. New forecast software is allowing the agency to break out of the days when weather reports were sent by “the wire” over teleprinters, which were basically typewriters hooked up to telephone lines. Teleprinters only allowed the use of upper-case letters, and while […]

Gravity waves. 5 Sigma results

The announcement indicates that gravity waves have been detected. The source of the waves is the collision of two black holes each with a mass of tens of times that of the sun. In the collision, an amount of mass was lost equivalent to several times that of the sun. This loss of mass was […]

Transtronics Wiki

It was a link to the capacitor codes page that got me started on the TransWiki. A look at the sealed lead acid page indicated that the technical expertise was up there, too. There’s a good range of information on  the Wili from paint primers and solvents to KiCad information. The company sells industrial level […]

Literacy: 17 Equations

Andy Kiersz presents The 17 equations that changed the course of history at Business Insider In 2013, mathematician and science author Ian Stewart published a book on 17 Equations That Changed The World. We recently came across this convenient table on Dr. Paul Coxon’s twitter account by mathematics tutor and blogger Larry Phillips that summarizes […]

Math education

In a discussion between Dave Jones and Jack Ganssle (YouTube) the topic of engineering education came up. This centered on the requirements for calculus despite neither of these experienced electronics engineers recalling having ever used integrals or differentials in their careers. The issue is one of training versus education. Engineering curriculum in colleges is particularly […]
