This is my model of SpaceX's Falcon 9 rocket, made for [Rocket Explorer](https://www.patreon.com/stanleycreative), my PC and virtual reality rocket viewer experience.

Falcon 9 is a two-stage-to-orbit medium lift launch vehicle designed and manufactured by SpaceX in the United States. It is powered by Merlin engines, also developed by SpaceX, burning liquid oxygen and rocket-grade kerosene propellants. Its name is derived from the Millennium Falcon and the nine engines of the rocket's first stage.

This bowl with an X-shaped handle can be dated to c. 50 BC-200 AD, i.e., [Late Pre-Roman Iron Age or Early Roman Iron Age](https://bit.ly/3vucSEX). It was found in [Gårdby parish](https://bit.ly/3hrP1gS) on the island of Öland. It belongs to a type of fine ware with carefully polished surface and a delicately incised décor. The black surface is a result of firing in a reducing atmosphere, in other words, the oxygen supply has been restricted during the firing. It is made in a style typical for Southern Scandinavia, Northern Germany and Poland. The bowl has probably been used as a drinking vessel at feasts, dinners and during rituals.

This 3D model represents the heart and lungs of a rabbit (Oryctolagus cuniculus), created with a focus on anatomical accuracy and educational clarity. The model demonstrates the close anatomical relationship between the cardiovascular and respiratory systems in a small mammal.

The heart shows realistic external morphology, including atrial and ventricular regions, while the lungs display correct lobation, size, and positioning relative to the heart. Together, these organs help illustrate how oxygenated blood circulation and respiration are functionally connected in mammals.

Rabbit Lungs

This disease involves inflammation in the lung's interstitial tissue due to various causes, causing the interstitial walls to thicken and harden (fibrosis), which impairs oxygen uptake. Because the blood cannot absorb enough oxygen to match the increased blood flow during physical activity, the oxygen level in the blood (oxygen saturation: SpO₂) drops significantly, leading to severe shortness of breath.

In total anomalous pulmonary venous return, the pulmonary veins do not return to the left atrium. In the infracardiac (meaning “below the heart”) type, the pulmonary veins drain to vessels in the abdomen with the oxygenated blood returning to the right side of the heart. The only way for blood to get to the left side of the heart is by crossing through an atrial septal defect (ASD) between the top two chambers. 
Sometimes the abnormal pathway that drains the pulmonary veins is too small leading to what is called “obstruction”, where the blood cannot flow normally throughout the body and babies can become very sick in these cases. Obstruction is more common with the infracardiac type.

TAPVR Infracardiac

The Heart is a muscular pump that circulates blood through the body, delivers oxygen and nutrients to 
tissues while removing carbon dioxide and metabolic waste. It maintains blood pressure and ensures 
continuous perfusion of organs essential for survival.

In total anomalous pulmonary venous return the pulmonary veins do not return to the left atrium. In the supracardiac (meaning “above the heart”) type, the pulmonary veins drain to vessels located above the heart with the oxygenated blood returning to the right side of the heart. The only way for blood to get to the left side of the heart is by crossing through a hole (an atrial septal defect or ASD) between the top two chambers (atria) to reach the left side of the heart. 

Sometimes the abnormal pathway that drains the pulmonary veins is too small leading to what is called “obstruction”, where the blood cannot flow normally throughout the body and babies can become very sick in these cases.

TAPVR (Supracardiac)

Transposition of the great arteries (TGA) occurs when the two main arteries are blood vessels leaving the heart or reversed and there is a hole in the wall between the right and left ventricle called a ventricular septal defect (VSD). The pulmonary artery arises from the left ventricle (instead of the right), sending oxygen-rich blood back to the lungs. The aorta arises from the right ventricle (instead of the left), sending oxygen-poor blood back to the body. This misrouting stops oxygen from being delivered to the body’s tissues and organs and can be life-threatening. The VSD can allow the for the deoxygenated and oxygenated blood to mix. Babies can look blue, especially around the lips and nails. They can have a fast heart rate, fast breathing, and poor feeding.

Transposition of the Great Arteries with VSD

Tricuspid atresia is a heart condition where the tricuspid valve doesn’t develop properly. This prevents blood from flowing from the right atrium to the right ventricle. Instead, blood is forced through an atrial septal defect from the right atrium to the left atrium and left side of the heart. The right ventricle, which normally pumps blood to the lungs, is often underdeveloped and very small (hypoplastic). This makes it difficult for blood to reach the lungs to pick up oxygen. A ventricular septal defect is often present. There can be other differences in the heart that can occur with tricuspid atresia. Your medical team will let you know if there are any other differences that your baby’s heart may have.

Tricuspid Atresia

Hypoplastic Left Heart Syndrome (HLHS) is a heart condition where the mitral and aortic valves don’t develop properly. The left ventricle and aorta are also underdeveloped and very small (hypoplastic). This prevents oxygenated blood from reaching the body. Instead, blood is forced through a hole (an atrial septal defect) from the left atrium to the right atrium with blood reaching the aorta though the pulmonary artery and ductus arteriosus (a connection between the aorta and pulmonary artery) to reach the body. There can be other differences in the heart that can occur with HLHS. Your medical team will let you know if there are any other differences that your baby’s heart may have.

Blood that has travelled through the body enters the right atrium via the superior and inferior caval vein. It then travels to the right ventricle, passing the tricuspid valve. It is then pumped into the pulmonary artery, towards the lungs. In the lungs, oxygen is bound to the blood; it becomes oxygen-rich. Subsequently, the oxygen-rich blood enters the left atrium. Passing the Mitral valve, the blood enters the left ventricle. The left ventricle pumps the blood into the aorta, upon which it travels to all the organs and tissues in the body, providing them from oxygen. Once it has done so, it travels back to the right atrium.

Tetralogy of Fallot (TOF) is a set of 4 changes to the heart that include narrowing of the pulmonary artery (pulmonary stenosis), a hole in the ventricular septum (ventricular septal defect or VSD), the aorta moving towards the right side of the heart (“overriding aorta”), and thickening of the right ventricle (right ventricular hypertrophy).

The baby’s symptoms will depend on the severity of the pulmonary stenosis. With severe pulmonary stenosis, less blood will be able to reach the lungs and the baby’s blood oxygen levels will be lower. Sometimes “Tet spells” can occur when there is suddenly less blood going to the lungs, and these can be an emergency.

Some babies may have less severe pulmonary stenosis and can have blood oxygen levels that are closer to typical for a baby.

Coal is a hard rock which can be burned as a solid fossil fuel. It is mostly carbon but also contains hydrogen, sulphur, oxygen and nitrogen. It is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top.

Ball and stick 3D model of the water molecule (H2O) free for download.
Molecular structure in this model is scientifically accurate (104.5 degree).

The H2O molecule is also known as the water molecule. It is composed of two hydrogen atoms and one oxygen atom. The molecular weight of this compound is 18 g/mol, and it has a molar mass of 18 g/mol. This means that 1 mol H2O contains 60218000 grams (6 × 1023) molecules.
The H2O molecule has a linear geometry and a straight line bonding between each of the atoms (on average 137 pm). The interatomic distance in hydrogen is very small (75 pm), and oxygen is relatively big (96 pm). There are two molecules in the centre of this model, and they are bound by strong interactions. Also, they can move themselves freely in all directions following their binding interactions. The most important feature of this 3D model is that it shows clearly lines of symmetry.
