What is a dishwasher salt?

You have used dishwasher salt, ever wondered what is it ?

Dishwasher salt is a particular grade of granulated, crystalline sodium chloride intended for regenerating the water softener circuit of household or industrial dishwashers. Analogous to water softener salt, dishwasher salt regenerates ion exchange resins, expelling the therein trapped calcium and magnesium ions that characterize hard water. Dishwater salt granules are larger than those of table salt. The granule size ensures that the salt dissolves slowly, and that fine particles do not block the softener unit.

Dishwasher salt is unsuitable for cooking as it is not considered food grade and therefore may contain toxic elements.

If a dishwasher has a built-in water softener there will be a special compartment inside the dishwasher where the salt is to be added when needed. This salt compartment is separate from the detergent compartment, and generally located at the bottom of the wash cabinet (this is below the bottom basket). On most dishwashers, an automatic sensing system will notify the user when more dishwasher salt is required.

If the dishwasher has run out of the salt that regenerates the ion exchange resin that softens the water, and the water supply is "hard", limescale deposits can appear on all items, but are especially visible on glassware.

In areas with soft water there is no need to use dishwasher salt for the machine to work. There is an option to adjust the water hardness making the machine to use no amount of salt brine for every dish cycle.

Aditya L1 India's Mission to Sun

 India has launched it's indigenous mission Aditya L1 from Sriharikota on 2nd September 2023 to study the Sun.

The Satellite is expected to exit Earth's gravity on 16 days. While it may take around 100 days to reach the L1 orbit around the Sun. I wondered what's so special about L1 Lagrange orbit? Why can't it use any random orbit? I found some interesting information, this post summarizes it.

What is a Lagrange Point?

Source: NASA/WMAP Science Team

Published: March 27, 2018

What are they?

Lagrange Points

Lagrange points are positions in space where objects sent there tend to stay put. At Lagrange points, the gravitational pull of two large masses precisely equals the centripetal force required for a small object to move with them. These points in space can be used by spacecraft to reduce fuel consumption needed to remain in position.

Above description highlights the importance of using the Lagrange point to deploy such observers. 

Lagrange Points are positions in space where the gravitational forces of a two body system like the Sun and the Earth produce enhanced regions of attraction and repulsion. These can be used by spacecraft to reduce fuel consumption needed to remain in position.

Lagrange points are named in honor of Italian-French mathematician Josephy-Louis Lagrange.

There are five special points where a small mass can orbit in a constant pattern with two larger masses. The Lagrange Points are positions where the gravitational pull of two large masses precisely equals the centripetal force required for a small object to move with them. This mathematical problem, known as the "General Three-Body Problem" was considered by Lagrange in his prize winning paper (Essai sur le Problème des Trois Corps, 1772).

Of the five Lagrange points, three are unstable and two are stable. The unstable Lagrange points - labeled L1, L2 and L3 - lie along the line connecting the two large masses. The stable Lagrange points - labeled L4 and L5 - form the apex of two equilateral triangles that have the large masses at their vertices. L4 leads the orbit of earth and L5 follows.

The L1 point of the Earth-Sun system affords an uninterrupted view of the sun and is currently home to the Solar and Heliospheric Observatory Satellite SOHO.

The L2 point of the Earth-Sun system was the home to the WMAP spacecraft, current home of Planck, and future home of the James Webb Space Telescope. L2 is ideal for astronomy because a spacecraft is close enough to readily communicate with Earth, can keep Sun, Earth and Moon behind the spacecraft for solar power and (with appropriate shielding) provides a clear view of deep space for our telescopes. The L1 and L2 points are unstable on a time scale of approximately 23 days, which requires satellites orbiting these positions to undergo regular course and attitude corrections.

L3 is of less use as it lies behind Sun.

The L4 and L5 points are home to stable orbits so long as the mass ratio between the two large masses exceeds 24.96. This condition is satisfied for both the Earth-Sun and Earth-Moon systems, and for many other pairs of bodies in the solar system. Objects found orbiting at the L4 and L5 points are often called Trojans after the three large asteroids Agamemnon, Achilles and Hector that orbit in the L4 and L5 points of the Jupiter-Sun system. (According to Homer, Hector was the Trojan champion slain by Achilles during King Agamemnon's siege of Troy). There are hundreds of Trojan Asteroids in the solar system. Most orbit with Jupiter, but others orbit with Mars. In addition, several of Saturn's moons have Trojan companions.

In 1956 the Polish astronomer Kordylewski discovered large concentrations of dust at the Trojan points of the Earth-Moon system. The DIRBE instrument on the COBE satellite confirmed earlier IRAS observations of a dust ring following the Earth's orbit around the Sun. The existence of this ring is closely related to the Trojan points, but the story is complicated by the effects of radiation pressure on the dust grains.

In 2010 NASA's WISE telescope finally confirmed the first Trojan asteroid (2010 TK7) around Earth's leading Lagrange point.

Finding the Lagrange Points

The easiest way to understand Lagrange points is to think of them in much the same way that wind speeds can be inferred from a weather map. The forces are strongest when the contours of the effective potential are closest together and weakest when the contours are far apart.

Mango festival Lalbagh 2023

Yesterday I visited Lalbagh for Mango festival. This is a yearly festival held in the month of June. 

 There were all varieties of mangoes for sale, with farmers from different districts like Ramanagaram, Kolar around Bangalore.

The profits directly go to the farmers who grow the trees as there are no middle men.

A bit of context for the festival:

The Lalbagh Mango Festival, also known as the Lalbagh Mango Mela, is an annual event held in the city of Bangalore, Karnataka, India.

AI and software development

Recently I came across a post on whether AI will replace software developers.

You might have heard about ChatGPT the AI library or Github's co pilot. All the developers are scared that soon their jobs will be replaced by AI. Some have predicted that to happen by year 2030. 

So what is the threat?

Day by day no of software companies are growing and so the no of developers in market as the new lot of freshers are entering the market. 

The scale with which the AI tools are improving is tremendous. Eventually good code is just few lines of structured program. And the amount of existing code available in code repositories like github is huge enough to train the AI.

Over the coming years AI can be as good as developer with experience of 50 years!

Following areas are under immediate threat

1. Code generation 

2. Testing & debugging 

3. project management

Following professions are safe from AI

1. Creative 

2. Healthcare

3. Skilled workers like welders, plumbers

4. Education 

5. Research and development 

6. Counselling
