A percentage of each payment withheld by the client until the work is demonstrably complete and any defects appearing within an agreed period have been corrected — an incentive for the contractor to
A detailed written description of exactly what is to be done, item by item — and it is the single most effective protection against disputes on a building project, because most disputes are about
Different professions with different training, different legal protections and different jobs — and engaging the wrong one wastes money and time. Architect. Designs buildings and spaces, prepares
Shaka kaSenzangakhona (c. 1787–1828) transformed the Zulu from a small chiefdom into a dominant regional power — and almost everything commonly said about him derives from sources that are
Alexander von Humboldt (1769–1859) was a Prussian naturalist and explorer who established the idea that nature is an interconnected system — a conception so thoroughly absorbed into modern thinking
Yes — and the measurement was remarkably good, achieved with geometry, a well and the distance between two cities, around 240 BC. The observation he started from. In Syene — modern Aswan — at noon on
Very little of the popular version survives contact with the evidence — and the most repeated element, the romance, is an invention, while the historical reality is considerably darker. Who she was.
Yes. She co-patented a frequency-hopping system for torpedo guidance that anticipated techniques underlying modern wireless communication — and the popular framing that she "invented Wi-Fi"
Toussaint Louverture (c. 1743–1803) led the Haitian Revolution — the only slave revolt in history to produce a lasting independent state — and his military and political achievement was accomplished
Sejong (1397–1450), fourth king of Korea's Joseon dynasty, is remembered principally for commissioning Hangul — a writing system designed deliberately and from first principles, which is
The truth is more complicated than either the heroic or the dismissive version, and the honest answer is that her data was used without her knowledge or consent — which is a serious matter regardless
Ibn Sina (c. 980–1037), known in the Latin West as Avicenna, was a Persian polymath whose medical encyclopaedia was a standard European university textbook for six centuries — an influence few works
Mary Anning (1799–1847) was a fossil collector and palaeontologist from Lyme Regis whose discoveries fundamentally changed scientific understanding of the past — and who was excluded from the
A formulary is an approved list of medicines a health organisation supports prescribing — the mechanism by which a large system applies consistent, evidence-based and cost-conscious decisions rather
There is no absolute legal right to a second opinion on the NHS — but requests are commonly accommodated, and knowing how to ask makes a considerable difference. The position. NHS guidance and
Different qualifications and different legal authority — and the roles have changed substantially, with many pharmacists now able to prescribe, which is not widely realised. Pharmacist. A registered
England charges a flat fee per item, with extensive exemptions — and the rest of the UK charges nothing, which is the difference most people are unaware of until they move. The four-nation position:
By making a request to whoever holds them — and since data protection law changed, it is free and does not require a reason, which is a significant improvement on the previous position. The right.
That a person understands what is proposed, the material risks, and the alternatives, and agrees voluntarily — and the legal standard in the UK changed significantly in 2015, in a way that shifted
A clinical decision recorded in someone's notes that cardiopulmonary resuscitation should not be attempted if their heart stops — and it is widely and distressingly misunderstood as meaning something
An urgent referral pathway for patients with symptoms that could indicate cancer, requiring them to be seen by a specialist within two weeks — and the most important thing to understand is that it is
Levels of specialisation and how you reach them — a structure designed so that most problems are dealt with close to home by generalists, and specialist capacity is reserved for what needs it.
By assessing whether a treatment represents an acceptable use of limited resources — combining how well it works with what it costs, since a health service with a fixed budget funding one thing
A bill introduced by an MP or peer who is not a government minister — and a small number do become law, though the mechanisms that allow it are narrow and easily obstructed. The three routes in the
A document setting out the standards of conduct expected of ministers — and the answer to who enforces it is the source of the persistent criticism: the Prime Minister, who is also bound by it. What
Someone who accompanies a litigant in person in court to provide assistance — taking notes, offering quiet advice and helping with papers — without being a legal representative. Where the name comes
By applying published guidelines to the specific case — a structured process that is considerably more constrained than the common perception of judges choosing freely. The Sentencing Council. An
Three organisations frequently conflated: territorial police forces investigate crime locally; the National Crime Agency tackles serious and organised crime nationally; and the Independent Office for
Because populations move, and equal representation requires constituencies to contain broadly equal numbers of electors — so boundaries must be revised periodically or votes become unequal in weight.
A by-election fills a single vacant parliamentary seat between general elections; a recall petition is the mechanism by which constituents can trigger one where their MP has met specified conditions.
That officials serve the government of the day — whichever party forms it — with equal commitment, and do not allow personal political views to affect their work. It is a constitutional principle
Organisations carrying out public functions at a distance from ministers — and the deliberate distance is the point, though it creates a genuine accountability question that has never been fully
Because the Freedom of Information Act contains a set of exemptions, some absolute and some qualified — and the majority of refusals rely on a small number of them. The basic right. Anyone, anywhere,
By recognising that different plants fail for different reasons — some are killed by frost, some by winter wet, and some simply by being too cold for too long — and the right protection depends on
By building something that suits the animals rather than the gardener — and the two decisions that matter most are shallow sloping edges and no fish, both of which are frequently got wrong. Why ponds
A grouping indicating when a variety flowers, used to work out which fruit trees can pollinate each other — and for many fruits the answer is yes, you need a compatible partner, though not always one
It is biennial bearing — a self-reinforcing cycle in which a heavy crop in one year prevents flower bud formation for the next, producing alternating years of glut and almost nothing. The mechanism.
Far fewer than a decade ago — a large number of active substances have been withdrawn from the amateur market following reviews of their effects on health, on pollinators and on water, and the
It has reverted — produced growth without the variegation — and if it is not removed it will take over the plant entirely, because the green growth has a genuine advantage. Why variegation exists.
Two propagation methods that avoid the difficult part of taking cuttings, because the new plant stays attached to the parent or already has roots. Layering. A stem is encouraged to root while still
By removing a piece of stem and inducing it to produce roots — and the type of cutting is determined by how mature the wood is, which in turn determines when you take it and how you treat it. Why it
Size and stage of development, which determine the price, how much care they need, and how soon they will do anything. Seeds. Cheapest by a wide margin, greatest choice of varieties, and the most
A plant lifted from the ground during dormancy and sold without any soil around its roots — cheaper, frequently establishing better than a potted equivalent, and available only for a few months a
Because a launcher is not a convenience feature — it is a direct relationship with the customer, and the commercial value of that relationship is the reason every substantial publisher wants one.
They exist because online games stop working when their servers are switched off, and their legal position is genuinely uncertain rather than clearly settled either way. What they are. Independently
A closed competition with permanent participating organisations who bought in, versus an open structure where any team can qualify by performance — and the difference determines who bears the risk
Options addressing the actual barriers rather than a single difficulty slider — and the field has advanced substantially, with established guidelines setting out what is expected. Visual: Adjustable
Save files stored on a remote service so progress follows you between devices — and conflicts arise because the system must decide which of two versions is correct, which it frequently cannot do
Because without it, a game where the objective is to be the last player alive would reward hiding — and the shrinking zone is a design solution to a problem that would otherwise make the format
Because a recurring cycle with a deadline solves several commercial and design problems at once — and understanding which is which makes the mechanics considerably more legible. What a season
