The slide rule, also known colloquially in the United States as a slipstick, is a mechanical analog computer. As graphical analog calculators, slide rules are closely related to nomograms, but the former are used for general calculations, whereas the latter are used for application-specific computations.
The slide rule is used primarily for multiplication and division, and also for functions such as exponents, roots, logarithms, and trigonometry, but typically not for addition or subtraction. Though similar in name and appearance to a standard ruler, the slide rule is not meant to be used for measuring length or drawing straight lines.
Slide rules exist in a diverse range of styles and generally appear in a linear or circular form with a standardized set of markings (scales) essential to performing mathematical computations. Slide rules manufactured for specialized fields such as aviation or finance typically feature additional scales that aid in calculations particular to those fields.
At its simplest, each number to be multiplied is represented by a length on a sliding ruler. As the rulers each have a logarithmic scale, it is possible to align them to read the sum of the logarithms, and hence calculate the product of the two numbers.
The Reverend William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier. Before the advent of the electronic calculator, it was the most commonly used calculation tool in science and engineering. The use of slide rules continued to grow through the 1950s and 1960s even as computers were being gradually introduced; but around 1974 the handheld electronic scientific calculator made them largely obsolete and most suppliers left the business.

Full moon rising behind the Spinnaker Tower at Portsmouth Harbour.
Ever get the idea for a particular image in your head, and can’t let it go, despite your experiences and common sense suggesting that you are flogging a dead horse?
Well, this is mine.
I’ve wanted to capture a full moon rising behind the viewing deck of the 170 metre tall Spinnaker Tower for the last couple of years. Several planned attempts were cancelled due to cloud cover, and several disappointments as my schoolboy trigonometry failed to calculate correctly the timing of the moon behind the tower. My long suffering pal Dave (Solent Poster) has been dragged over to darkest Gosport on several occasions, all to no avail. Finally, the Hunter’s Moon, looked like it may yield the image I was after. So yet again we found ourselves at Gosport seafront, set up our gear, and waited. The moon rose where I had calculated which was a first in itself (and quite a surprise!), but initially it looked like its path would be too low, however the promenade gave the opportunity to shuffle along it until finally, at long last, the moon was behind the deck. Unfortunately by then we were at the end of blue hour and the huge dynamic range between the bright moon and dim tower was so many stops of light that it rendered the images unusable, so I have had to resort to blending two images from the shoot together. I still want to capture it in a single frame, so sorry Dave, we’ll have to keep trying!
Table Mountain is a flat-topped mountain forming a prominent landmark overlooking the city of Cape Town in South Africa. It is a significant tourist attraction, with many visitors using the cableway or hiking to the top. Table Mountain National Park is the most visited national park in South Africa, attracting 4.2 million people every year for various activities. The mountain has 8,200 plant species, of which around 80% are fynbos, meaning fine bush. It forms part of the Table Mountain National Park, and part of the lands formerly ranged by Khoe-speaking clans, such as the !Uriǁʼaes. It is home to a large array of mostly endemic fauna and flora. Its top elevates about 1.000 m above the surrounding city, making the popular hike upwards on a large variety of different, often steep and rocky pathways a serious mountain tour which requires fitness, preparation and hiking equipment.
The main feature of Table Mountain is the level plateau approximately three kilometres from side to side, edged by steep cliffs. The plateau, flanked by Devil's Peak to the east and by Lion's Head to the west, forms a dramatic backdrop to Cape Town. This broad sweep of mountainous heights, together with Signal Hill, forms the natural amphitheatre of the City Bowl and Table Bay harbour. The highest point on Table Mountain is towards the eastern end of the plateau and is marked by Maclear's Beacon, a stone cairn built in 1865 by Sir Thomas Maclear for trigonometrical survey. It is 1,086 metres above sea level, and about 19 metres higher than the cable station at the western end of the plateau.
The cliffs of the main plateau are split by Platteklip Gorge ("Flat Stone Gorge"), which provides an easy and direct ascent to the summit and was the route taken by António de Saldanha on the first recorded ascent of the mountain in 1503.
The flat top of the mountain is often covered by orographic clouds, formed when a southeasterly wind is directed up the mountain's slopes into colder air, where the moisture condenses to form the so-called "table cloth" of cloud. Legend attributes this phenomenon to a smoking contest between the Devil and a local pirate called Van Hunks. When the table cloth is seen, it symbolizes the contest.
Table Mountain is at the northern end of a sandstone mountain range that forms the spine of the Cape Peninsula that terminates approximately 50 kilometres to the south at the Cape of Good Hope and Cape Point. Immediately to the south of Table Mountain is a rugged "plateau" at a somewhat lower elevation than the Table Mountain Plateau, called the "Back Table". The "Back Table" extends southwards for approximately 6 km to the Constantia Nek-Hout Bay valley. The Atlantic side of the Back Table is known as the Twelve Apostles, which extends from Kloof Nek (the saddle between Table Mountain and Lion's Head) to Hout Bay. The eastern side of this portion of the Peninsula's mountain chain, extending from Devil's Peak, the eastern side of Table Mountain (Erica and Fernwood Buttresses), and the Back Table to Constantia Nek, does not have a single name, as on the western side. It is better known by the names of the conservation areas on its lower slopes: Groote Schuur Estate, Newlands Forest, Kirstenbosch Botanical Gardens, Cecilia Park, and Constantia Nek.

And this is my landscape and the colours I deal with a large portion of the year. You learn to master the white balance, overcompensate with slight adjustments. Just being behind the lenses is all a person need to escape from any pressing obligations. All you see and focus on is whatever in front of your eyes. I like the action of scouting and taking photos more than the actual development of a picture - processing & organizing & posting on occasions. Sharing and selling are not on table right now. True, Sometimes I'm curious to see the final product, but it's not the goal, it is the journey that counts.
The creations of whiteouts - wind, snow and barren fields/open spaces, might lead you to places you haven't intended to be in the first place - you might become disoriented for a bit if it's a too long a stretch. You learn to compensate, drive according to conditions. But even when you're lost you're found. All you need is your core, and it doesn't matter where you are, eventually you'll find a way. Your way. Capish? Nah. I'm just blabbering into the howling wind. You can do that when you're lost, no one will know it's you. The freedom eh?

Cap Blanc Nez (literally "Cape White Nose" in English; from Dutch Blankenesse, white headland) is a cape on the Côte d'Opale, in the Pas-de-Calais département, in northern France. The cliffs of chalk are very similar to the white cliffs of Dover at the other side of the Channel in England. Cap Blanc Nez does not protrude into the sea like a typical cape, but is a high point where a chalk ridge has been truncated by the sea, forming a cliff that is topped by the obelisk of the Dover Patrol Monument, commemorating the Dover Patrol which kept the Channel free from U-boats during World War I.
Cap Blanc Nez was a vital measuring point for the eighteenth-century trigonometric survey linking the Paris Observatory with the Royal Greenwich Observatory. Sightings were made across the English Chanel to Dover Castle and Fairlight Windmill on the South Downs. (Wikipedia)
Nikon D810 | 80-400 | 400mm | f/8 | Foreground: 2.5 seconds @ ISO 1600 | Moon: 1 second @ ISO 3200
September 2015’s blood moon eclipse rising over Mount Shuksan in Washington State, shot on a rented 80-400mm. This is a composite of two images – one to capture the foreground while there was still enough light and another for the moon as it rose above the mountain about 20 minutes later. This shoot was planned out in advance with the amazing Photo Pills app and a bit of trigonometry. I'd be happy to share the spreadsheet for anyone who is interested.
I'm about 30% into a much more ambitious composite of the lunar eclipse. Stay tuned.

Since 2019, I've had the idea of photographing a moonbow on Yosemite Falls while a hiker created a light trail up the trail next to it. My first attempt at this shot was canceled by the pandemic, and then the next few years were too dry for good moonbows. This year's record snowpack finally enabled this photo.
I wrote a Python code to predict where and when rainbows and moonbows could be possible. This involved some fun spherical trigonometry and vector math that I hadn't needed in a while. I was worried that I might have made an error and a whole group of people might make a trip based upon my erroneous predictions. Fortunately, my predictions were accurate, the moonbow appeared right on schedule, and it lasted about 20 minutes when viewed from Sentinel Dome.
Jon-Kyle Mohr and I carried six cameras up to Sentinel Dome, across the valley from Yosemite Falls. Griff Joyce and Mark Vierra, of the Half Dome 50/50/50 adventure and the Yosemite lunar eclipse trip, hiked up Yosemite Falls at the right time. An 82% moon illuminated the scene.
Clouds obscured the sky above, blocking the moon, and filled the valley, blocking my view of the falls. Following some desperate prayers, they cleared exactly as the moonbow occurred. The photo was possible after all!
This is the first of several posts I'll make, since I have a number of angles and variations on this photo. I stacked a bunch of 20-second exposures to produce the light trail. A single exposure was used for the moonbow.
Zodiacal light and the winter band of the Milky Way creates an almost perfect right triangle over this desert ghost town.
A few things to point out in this vertical panorama, is the obvious beam of light on the left of the frame known as Zodiacal light. The reddish smudge (upper mid left) is the California Nebula, and peeking out from behind the jail is the Andromeda Galaxy. You can also see a couple of the other buildings still standing near the base of the mountain.

Kangchenjunga is the third highest mountain in the world. It rises with an elevation of 8,586 m (28,169 ft) in a section of the Himalayas called Kangchenjunga Himal that is limited in the west by the Tamur River and in the east by the Teesta River. The Kangchenjunga Himal is located in eastern Nepal and Sikkim, India.
Until 1852, Kangchenjunga was assumed to be the highest mountain in the world, but calculations based on various readings and measurements made by the Great Trigonometrical Survey of India in 1849 came to the conclusion that Mount Everest, known as Peak XV at the time, was the highest. Allowing for further verification of all calculations, it was officially announced in 1856 that Kangchenjunga is the third highest mountain

Compass, Slide Rule
A slide rule, also known as a slide ruler or a slipstick, is an extremely complex ruler that functions as an analog computer. By sliding various components of the ruler to align with one another, a slide rule can compute products, roots, logarithms, and the result of trigonometric functions.

Cylindrical Slide Rule.
When I was about fourteen I remember my maths master bringing in the first electronic calculator I had ever seen. It could do addition, multiplication, division and subtraction and had one memory. It cost around £300 in today’s money. By the end of my undergraduate studies I had a programmable scientific calculator that handled trig functions and statistics and cost only £30.
In the sixth form (i.e. years 12 & 13) we used slide rules and books of tables for calculation as calculators weren’t generally allowed in examinations. The slide rule I had was an advanced one, double-sided with trigonometric, log and exponential functions built in.
In many ways slide rules remain superior to calculators. They are fast, intuitive and less prone to errors of data entry. In experienced hands fairly complicated calculations can be done rapidly. They also make it easier to estimate answers and they teach you to handle the powers of ten in a calculation so that they become second nature. These skills become very important at university in a complex subject like Physics as you need to work out whether you are on the right track quickly when you are working a problem.
All slide rules work on the same principle. You can save doing a multiplication of two numbers by converting the numbers to their logarithms and then adding those together, finally converting back to ordinary numbers. In this way a multiplication becomes a simple addition which is way easier. Slide rules work by converting the log numbers into lengths on the rule and by sliding one bit of rule against another you can add the lengths (literally) and then read back the total length to convert back to the normal numbers.
The main drawback with slide rules is precision. An ordinary slide rule can work to about three significant digits whereas calculators work at eight or more. Of course precision doesn’t buy you much if you have entered the wrong figures into the calculator in the first place.
The precision is determined by the length of the slide rule: they’re normally about a foot long. Any longer and you have problems getting them in your briefcase :)
This is an image of my father’s precision slide rule. It gets around the length problem by spiralling the scale around a cylinder. The cylinder is in three parts that can rotate independently the scales on the top and bottom parts with a sliding sleeve in between. Collapsed down it is about six inches long, but the scale is equivalent to a slide rule about five and a half feet in length!
This is a picture of the top scale and part of the central sleeve, on top of some of the instructions for the device (an Otis King model “L” if you are a detailophile :) ).
I created this for the Macro Mondays Back In The Day theme this week. The exposed area of the scale is 1.3 inches so we are within the limits for the group - yey! Also for 7DWF :)
Thank you for taking time to look. I hope you enjoy the image! Happy Macro Mondays!!

Kanchenjunga (Nepali: कञ्चनजङ्घा; Hindi: कंचनजंघा; Sikkimese: ཁང་ཅེན་ཛོཾག་), sometimes spelled Kangchenjunga, is the third highest mountain in the world, and lies partly in Nepal and partly in Sikkim, India. It rises with an elevation of 8,586 m (28,169 ft) in a section of the Himalayas called Kangchenjunga Himal that is limited in the west by the Tamur River, in the north by the Lhonak Chu and Jongsang La, and in the east by the Teesta River. It lies about 128 km (80 mi) east of Mount Everest.
Kanchenjunga is the second highest mountain of the Himalayas after Mount Everest. Three of the five peaks – Main, Central and South – are on the border between North Sikkim and Nepal. Two peaks are in the Taplejung District, Nepal.
Kangchenjunga Main is the highest mountain in India, and the easternmost of the mountains higher than 8,000 m (26,000 ft). It is called Five Treasures of Snow after its five high peaks, and has always been worshipped by the people of Darjeeling and Sikkim.
Until 1852, Kangchenjunga was assumed to be the highest mountain in the world, but calculations based on various readings and measurements made by the Great Trigonometrical Survey of India in 1849 came to the conclusion that Mount Everest, known as Peak XV at the time, was the highest.

Mount Everest, also known in Nepal as Sagarmāthā and in Tibet as Chomolungma, is Earth's highest mountain. It is located in the Mahalangur mountain range in Nepal.[8][9] Its peak is 8,848 metres (29,029 ft) above sea level.[1] It is not the furthest summit from the centre of the Earth. That honour goes to Mount Chimborazo, in the Andes.[10] The international border between China and Nepal runs across Everest's precise summit point. Its massif includes neighbouring peaks Lhotse, 8,516 m (27,940 ft); Nuptse, 7,855 m (25,771 ft) and Changtse, 7,580 m (24,870 ft).
In 1856, the Great Trigonometrical Survey of India established the first published height of Everest, then known as Peak XV, at 29,002 ft (8,840 m). The current official height of 8,848 m (29,029 ft) as recognised by China and Nepal was established by a 1955 Indian survey and subsequently confirmed by a Chinese survey in 1975. In 1865, Everest was given its official English name by the Royal Geographical Society upon a recommendation by Andrew Waugh, the British Surveyor General of India. Waugh named the mountain after his predecessor in the post, Sir George Everest, arguing that there were many local names, against the opinion of Everest.[

Dr. Honeydew: “Hello, Fozzie. Are you learning math today?”
Fozzie: “Oh, when I was younger, I learned about numbers. Today, when I need to know how many things I have, I can count on numbers to give me the total.”
Dr. Honeydew: “Did you learn more when you got older?”
Fozzie: “I tried learning how to work with triangles and make them into circles, but it was pointless.”
Dr. Honeydew: “What about work with equations?”
Fozzie: “My algebra teacher said she was better than my geometry teacher.”
Dr. Honeydew: “Why was that?”
Fozzie: “For one thing, we were always trying to solve for x, not so much for why. But she said she was better as the geometry teacher was too symbol-minded.”
Dr. Honeydew: “Did you study any trigonometry?”
Fozzie: “No, that was difficult to learn as it was in sine language.”
The position of the rainbow isn't ideal, but for the novelty of catching it from Southside Drive it's a fun variation.
This area was packed with photographers this year, which is very strange, given that moonbows are only visible as the colorful refracted light exits the water drops at 21 degrees off axis from the moon's direction. The colors are separated by fractions of a degree as white light goes from air to water and back to air after two reflections within the water drop. It's not like the rainbow simply exists there, and can be seen from all directions!
So photographers positioning themselves in other places is like shooting a game of pool blindfolded. Sure, you might get lucky from time to time, but you'll waste a lot of time too.
But even a broken clock is right twice a day (as long as it's not digital), so by all means, if you don't want to review the trigonometry (or find a high school student who will do the math for you), take all the "blind pool shots" you want, and see if you can get lucky!
What is this? This is not a portrait! Not really - but I shot this last week on my way to a portrait shooting. That makes it at least half a portrait :D
