ItÕs 30+ years later, but still some of the same optics are available.  And there still is a need for a real how-to book on building simple optical devices like overhead projectors, opaque projectors, telescopes, collimators, magnifiers, etc.  I refer to this book when I need to solutions to the  problems controlling the laser beams in my holography lab.

In a statement on Friday, the US State Department said RT — previously known as Russia Today — had “moved beyond being simply a media outlet and has been an entity with cyber capabilities”.

“Our most powerful antidote to Russia’s lies is the truth,” Blinken said. “It’s shining a bright light on what the Kremlin is trying to do under the cover of darkness.”

They alleged the outlet also expanded its use of cyber-operations with a new unit with ties to Russian intelligence created last year.

“It is also engaged in information operations, covert influence, and military procurement. These operations are targeting countries around the world, including in Europe, Africa, and North and South America.”

Speaking to reporters about Friday’s sanctions, US Secretary of State Antony Blinken said the Russian state media outlet “wants its new covert intelligence capabilities, like its longstanding propaganda disinformation efforts, to remain hidden”.

The administration of US President Joe Biden — a staunch critic of his Russia counterpart, Vladimir Putin — has issued waves of sanctions against Russian individuals and companies since the war began in 2022.

One of the great features of this book is its formulae.  They take the Gausian form of the Simple Lens Formula and break it into all its permutations.  For instance, if you know the object distance and focal length for an imaging scenario, you can find the magnification by looking up the appropriate formula and plugging and chugging.  They also give examples of practical calculations for all formulae, using whole numbers so that it is easy to see the math in action.

Was someone either having fun with the addition of the beard on the original artwork, or was it a marketing move to make the SPOTSCOPE more attractive to hip peeping Toms?! Might there may be an even earlier edition without much in the way of sideburns? Have there ever been any sightings of more beards, moustaches, dueling scars or pirate patches over the eyes of other Edmund illsutrations?
