Key takeaways

Kastus belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Kastus to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Kastus from memory before moving on to harder problems.

Reference excerpt

Kastus Technologies is an Irish nanotechnology company based in Dublin.

History John Browne founded Kastus in 2014 in Dublin following 10 years of collaborative research with Dublin Institute of Technology. It was developed out of an increasing demand for a reduction in the spread of antibiotic-resistant infections commonly found on indoor surfaces. In October 2017, the Department of Health published “Ireland’s National Action Plan on Antimicrobial Resistance 2017-2020”, which highlighted the threat antimicrobial resistance poses and the urgent need for new technology to combat this. In April 2016, the Sligo Institute of Technology, which is funded by Kastus, announced the creation of a non-toxic antimicrobial nanotechnology, which Kastus plans to market globally. This research is supported by a €1.5 million funding investment from Atlantic Bridge. In 2018, Kastus partnered with Oman-based ceramic tile producer Al Maha Ceramics, which exports to 15 countries in Asia and Africa. The deal saw Kastus use its antimicrobial technology to produce a range of new tiles called iProtect. In 2020, Kastus developed antimicrobial and antiviral technology used on touch screens to prevent the spread of diseases such as COVID-19. Kastus was awarded EU funding to further develop and expand these technologies and their applications, and has partnered with companies such as Lenovo, In 2021, Kastus raised €5.65 million in a Series A round to build out its global commercial team to meet growing demand for its antiviral surface protection technology.

Worked examples

Example 1 — a first encounter with Kastus

Start with the simplest possible case. Write down what Kastus claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kastus before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kastus ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kastus

In research: Kastus appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Kastus in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Kastus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Dublin (city), Nanotechnology companies, so understanding it makes those chapters shorter.
In everyday life: Look for Kastus outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
