Flowering plants wiki
Flowers contain male and female parts that work together to reproduce seeds. Pollen from the male part must be transferred to the female part through pollination by wind or animals. This allows reproduction to occur, resulting in seeds protected inside fruits. Seeds are dispersed from the fruits and germinate into new plants when they receive water, nutrients, and the right temperature conditions. The plant life cycle then continues as seeds grow into new plants.
Types of soil
Soils are mixtures of rock particles, organic matter, air, and water that support plant growth. The type of soil depends on the size of its particles, with sandy soil having large particles and many air gaps allowing for good drainage, clay soil having tiny particles and few air gaps so it drains poorly, and silt soil being intermediate. Different plant types grow best in different soil types depending on their drainage and composition.
minerals and rocks
Minerals are found in rocks and there are over 3000 known types of minerals. Minerals have different properties like color, hardness, streak, and luster that can be used to identify them. There are three main types of rocks: igneous rocks which form from cooling magma or lava, sedimentary rocks which form from compressed and cemented sediment, and metamorphic rocks which form from other rocks being subjected to heat and pressure below the earth's surface. Common rocks like granite, shale, and marble are used for construction materials, building monuments, and other purposes due to their unique properties.

Thermal energy
Thermal energy is the energy of moving particles that causes heat. Heat is the transfer of thermal energy between objects when they are at different temperatures. The document discusses conductors and insulators - materials that easily allow heat to pass through them are conductors like metals and materials that do not are insulators like rubber, wood, and paper. Common examples of conductors and insulators are provided.
Air and water resistance
The document discusses different forces exerted by water and air. There are two main forces of water: upthrust force, which causes objects to float, and water resistance, which pushes against moving objects in water. Air also exerts forces, including air resistance, which slows down moving objects by pushing against them, with larger objects experiencing greater resistance. Air resistance can be useful, as seen with parachutes which use the force of air to slow a falling object.
Balanced unbalanced ,gravity ,friction
1) Forces cause objects to move or change their motion. Applying an unbalanced force makes an object start moving, while balanced or cancelled out forces will not cause motion.
2) Friction is a type of force that opposes motion when two surfaces are touching, causing moving objects to slow down and stop. The amount of friction depends on the surfaces and how rough or smooth they are.
3) Mass and gravity determine an object's weight, with heavier objects having greater weight. Weight can be measured using a force meter or spring scale.
Magnetic and non magnetic
The document discusses magnetic and non-magnetic materials. Magnetic materials include metals like iron, nickel, cobalt and steel that are attracted to magnets. Non-magnetic materials include aluminum, silver, gold, paper, glass, plastic, rubber and wood that are not attracted to magnets. It provides examples of different objects and whether they are magnetic or non-magnetic when tested with a magnet.
Magnet use
To safely handle magnets, wear protective eyewear and gloves to avoid injury from breaking or flying pieces. Handle magnets gently by slowly bringing them together and avoiding dropping or banging them, which can reduce their strength. Store magnets away from devices, tapes, cards, and screens where magnetic fields can cause damage or distortion. Also, keep magnets dry and do not heat them.
Magnet type + story
Magnets have been known since ancient times when a shepherd named Magnus discovered that an unusual black rock had the power to pull iron objects like his staff and sandal nails towards it. This became known as the first recorded discovery of a magnet. Different types of magnets exist, with some able to attract or repel other magnets depending on which poles (north or south) are placed close together. Magnets have been studied for centuries but still hold mysterious properties about the forces they exert.
Magnet 3
Magnets are made of iron, nickel, cobalt, or steel. To preserve a bar magnet long term, you should store it with another magnet to maintain its magnetic field. When a magnet breaks, its magnetic field also breaks into smaller fields in each broken piece. An electromagnet generates a magnetic field through a coil of wire when electric current passes through; placing an iron core inside the coil strengthens the magnetic field. Materials can be magnetic, like iron, cobalt, and nickel, or non-magnetic, like aluminum, copper, glass, plastic, and wood.
Magnet 2
The document discusses the properties of iron and magnets at the particle level. It asks questions about what iron particles look like, how iron is attracted to magnets, what magnets are made of, and how to preserve a bar magnet long-term. It prompts the reader to draw diagrams of magnetic fields with arrows and labels to illustrate the alignment of iron particles when brought near a magnet.
Series and parallel
The document discusses series and parallel circuits. It provides examples of series circuits with one path and defines that if one light bulb is removed, the circuit is open and other bulbs will not light. Parallel circuits are defined as having more than one path, and if one light bulb is removed, the current passes through another path and the other bulb will still light. The document draws examples of both series and parallel circuits.
Safety rules
This document provides safety tips for handling electricity, advising to not play with electric sockets or plugs, not to touch electricity with wet hands, and to avoid poking fingers or other objects into electric sockets, toasters, or other appliances.
Conductor and insulator
This document discusses series and parallel circuits and the properties of conductors and insulators. It explains that in a series circuit, if one bulb is removed the other bulb will not light, while in a parallel circuit the other bulbs will still light if one is removed. It provides examples of materials that are conductors, like silver, copper and aluminum, and insulators, like plastic, rubber and glass. It then has questions to determine if examples provided are conductors or insulators.
Circuit (symbols,dimmer and brighter)
This document discusses the basics of electricity and electrical circuits. It explains that electricity is the flow of electric charges through a wire, just as water flows through a river. An electrical circuit needs three main components - a power source like a battery, a load such as a light bulb, and wires or other connectors to complete the circuit. It also discusses concepts like open versus closed circuits, and how changing components like batteries or bulbs affects brightness. Symbols are introduced for common circuit elements. Worksheets are included to have the reader draw sample circuits.
Atom,static electricity
The document discusses the basics of static electricity and atoms. It explains that atoms are made up of positively and negatively charged particles that attract or repel depending on their charges. Static electricity occurs when objects come into contact and transfer electrons, resulting in an imbalance of charges. Examples given include rubbing a balloon or ruler to build up an excess of electrons, causing it to stick to other surfaces. Lightning is also described as a large-scale discharge of built up static charges between storm clouds and the ground.
Reversible and irreversible change
The document discusses reversible and irreversible changes. Reversible changes can go forward and backward, such as folding paper or melting butter. Irreversible changes cannot go backward, like burning wood or rusting iron. Examples are provided of changes that are reversible, like freezing orange juice or dissolving salt in water, and those that are irreversible, including burning a matchstick or toasting bread.
Reversible and Irreversible changes
This document discusses the differences between physical and chemical changes and provides examples of evidence of irreversible chemical changes. Specifically, it notes that physical changes are reversible while chemical changes are irreversible. It then lists four main types of evidence that can indicate an irreversible chemical change has occurred: 1) a change in color, 2) a change in scent, 3) the presence of bubbles or fizzing, and 4) heat being released or absorbed during the change. Examples like iron rusting and silver tarnishing are given as illustrations of changes in color, while toasting marshmallows represents a change in scent.
Food pyramid wiki
The food pyramid outlines the major food groups including carbohydrates, vitamins and minerals, protein, and oils. It recommends filling your plate with fruits, vegetables, dairy, and meat to create a balanced meal and get the necessary nutrients. A balanced meal incorporates foods from all the major food groups.
Teeth wiki
There are three main types of teeth: incisors, canines, and molars. Incisors are flat teeth located at the front of the mouth that cut food. Canines are sharp, pointed teeth on the sides of the mouth after the incisors that hold and tear food. Molars are flat, wide teeth located at the back of the mouth that grind and chew food. Humans have two sets of teeth, milk (baby) teeth and permanent teeth. Milk teeth number 20 total while permanent teeth number 32 total. Bacteria in the mouth feed on sugar from leftover food and produce acid that causes tooth decay if plaque is not removed by brushing.
Matter
Matter is anything that has mass and takes up space. There are three main states of matter: solids, liquids, and gases. The state that matter exists in depends on how closely or loosely packed the particles are and the strength of attraction between the particles. Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have indefinite shapes and volumes. Matter can change between states, such as ice melting into water when heat is applied, changing the phase from solid to liquid.
Teeth 2
This document describes the different types of teeth and their functions. It discusses the four types of teeth: incisors, which cut food; canines, which tear and hold food; premolars, which have a grinding function; and molars, which grind and chew food. It also notes that humans have two sets of teeth - milk (primary) teeth when young, which are later replaced by permanent adult teeth starting around age 6 or 7 years old.
Teeth 1
Teeth have the function of breaking down food into pieces small enough to swallow. There are different types of teeth suited to specific functions, such as incisors for biting, canines for tearing, and premolars and molars for grinding food. Teeth break down food through biting, tearing, and grinding motions.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Anti-Universe And Emergent Gravity and the Dark Universe
Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.
JAMES WEBB STUDY THE MASSIVE BLACK HOLE SEEDS
The pathway(s) to seeding the massive black holes (MBHs) that exist at the heart of galaxies in the present and distant Universe remains an unsolved problem. Here we categorise, describe and quantitatively discuss the formation pathways of both light and heavy seeds. We emphasise that the most recent computational models suggest that rather than a bimodal-like mass spectrum between light and heavy seeds with light at one end and heavy at the other that instead a continuum exists. Light seeds being more ubiquitous and the heavier seeds becoming less and less abundant due the rarer environmental conditions required for their formation. We therefore examine the different mechanisms that give rise to different seed mass spectrums. We show how and why the mechanisms that produce the heaviest seeds are also among the rarest events in the Universe and are hence extremely unlikely to be the seeds for the vast majority of the MBH population. We quantify, within the limits of the current large uncertainties in the seeding processes, the expected number densities of the seed mass spectrum. We argue that light seeds must be at least 103 to 105 times more numerous than heavy seeds to explain the MBH population as a whole. Based on our current understanding of the seed population this makes heavy seeds (Mseed > 103 M⊙) a significantly more likely pathway given that heavy seeds have an abundance pattern than is close to and likely in excess of 10−4 compared to light seeds. Finally, we examine the current state-of-the-art in numerical calculations and recent observations and plot a path forward for near-future advances in both domains.

How do you know your food is safe?
Last Friday was world World Food Safety Day, facilitated by the Food and Agriculture Organization of the United Nations (FAO) and the World Health Organization (WHO) in which the slogan rightly says, 'food safety is everyone's business'. Due to this, I thought it would be worth sharing some data that I have worked on in this field!
Working at Markes International has really opened my eyes (and unfortunately my friends and family 🤣) to food safety and quality, especially with my recent application work on ethylene oxide and 2-chloroethanol residues in foodstuffs, as of the biggest global food recalls in history was and is still being implemented by the Rapid alert system for food and feed (RASFF) in 2021, for high levels of these carcinogenic compounds.
The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆
Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4
