This document discusses measurements in our solar system and proposes representing it to scale in a classroom. It provides tables with the distances of planets from the sun in km and centimeters, and the diameters of planets in km. It suggests representing planets with different objects based on their size. It also introduces astronomical units and light years as alternative units of measurement for large distances, stating 1 AU is equal to 150 billion meters and 1 light year is equal to 64,000 astronomical units.
How many planets can we see with a naked eye? Five! Mercury, Venus, Mars, Jupiter and Saturn can all be spotted from Earth without the aid of a telescope or binoculars. Though in principle all five are visible, some are easier to find than others. Mercury is the trickiest planet to observe thanks to its small size and proximity to the Sun. Telescopic observations of the planet face the same problem.
But it is not only difficult to observe Mercury from the ground. Sending robotic explorers to the tiny planet is also tricky. Mercury is very fast. It is very energy consuming to get a spacecraft into orbit around Mercury. The amount of propellant needed could have taken you all the way to Jupiter (though Jupiter is 12 times farther away from the Earth than Mercury). Another challenge is the radiation from the Sun. Any spacecraft daring to get so close to our star will have to have a one of a kind heat protection to operate!
Unsurprisingly, Mercury is the least explored terrestrial planet in the Solar System. Our knowledge of it is very patchy and far from complete. Still, Mercury is a very interesting object and we want to study it despite all the difficulties. Yes, it is not surrounded by a swarm of moons. There are no rings, And it is unlikely that we will find any living things there. But this little planet can tell us a lot about our Solar System and explain how planets orbiting close to their stars form and evolve.

Is There another Orbit For The Moon Motion? Gerges francis
Paper Hypothesis No. (1)
-Another Orbit must be found for the moon motion.
Paper Hypothesis No. (2)
-An interaction is found between Jupiter and the Earth moon motions, this interaction shows that another orbit must be found for the moon motion –
Paper Objective
-The paper tries to prove that, there's an interaction between Jupiter and the moon motion.
-And
-Based on this interaction, Jupiter effect on the moon motion suggests that another orbit is required necessary for the moon orbital motion.

This discovery will resolve the long-pending controversy related to the "speed of Light" and will pave way for a leap progress in the science of Astrophysics.
Uranus Is Perpendicular On Earth Moon Orbit (II) Gerges francis
Paper Claim
-Uranus Axial Tilt created an angle = 91.1 degrees with the Earth Moon Axial Tilt
But
- Uranus Axial Tilt is perpendicular (90 degrees) on the moon orbit, at the radius Perigee Point (r= 0.363 mkm)
- This perpendicularity (90 degrees), Uranus Axial Tilt performed because of using the value (1.1 degrees) to create an angle between the moon orbit horizontal base and the horizontal level…
- The angle (1.1 degrees) effects causes the moon orbit regression (19 degrees) per year
Paper Conclusion
- The moon orbit regression is a result of Uranus Axial Tilt perpendicularity on The moon orbit.

In Table 19.1 are listed the average distance from the Sun, r , in Astronomical Units (AUs), and

The Milky Way Galaxy: A Dispersed Distribution of Mass Our solar system lies in the outskirts
of the Milky Way, a vast, rotating, disk-shaped assemblage of stars, gas, and dust more than
100,000 light-years across. Table 19.2 lists observational data for celestial objects found at
various locations within the Milky Way's disk: r is the object's distance, or radius, from the
galactic center, in units of kiloparsecs (kpc), where 1 kpc = 1 , 000 parsecs (about 3,260 light-
years), and v is the object's orbital velocity around the galactic center in kilometers per second (
km / s ) . Taken together, this array of orbital velocities traces out the Galaxy's pattern of
rotation. 3. Plot the galactic radius and velocity data from Table 19.2 on the axes of Figure 19.3

Paper Hypothesis
-There's Another Similar Orbit For The Moon Motion
The Hypothesis explanation
- The triangle ACE shows that, a double value of the triangle perimeter is used for geometrical necessities in the moon orbital motion
- i.e.
- While the (ACE) triangle perimeter = 943817 km, the geometrical structure of the moon orbit uses the value 1887634 km (= 2 x 943817 km) as one of the basic motion values.
- There's one more reason for this hypothesis, because the moon orbital motion space area contains (50%) of the Jupiter Whole Energy, that tells if the energy is transported to the moon orbit why just (50%) only?
- I suggest that
- Another similar orbit of the moon must be found which we can't see. This idea is supported by our previous argument, where the moon moves daily 2.58 mkm (as Earth) and because of the contraction this value became 2.41 mkm, So the tries to cover this difference (0.17 mkm) by its daily displacement (88000km) which is not enough and the moon needs to move another displacement (88000km) to cover the different distance, where this last displacement (88000km) we can't see, and based on that I suppose the moon must have another similar orbit through which the moon moves this additional displacement (88000km).
- The paper tries to prove this fact

Planck’s length is the scale in which the classical ideas of gravity and space-time cease to be valid and where uncertainty dictates the rules. This is the size of the information bits on the black holes event horizon and there is a good reason to assume that it is the size of the basic building blocks of the fabric of space. This article assumes three leading assumptions: 1. the quantization of space into a lattice (grid) of unit cells, which I will refer to as 3D voxels of space (voxels) in the size of Planck’s length in each dimension. 2. The quantization of time into Planck’s time sequences (pulses). 3. Light travels one space voxel for each time pulse. Based on these three assumptions, this article will show that the Newton gravitational constant (G) increases as the universe expands. This increase in the gravitational constant can illuminate some light on the mysterious dark matter.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

3. Changes to units of astronomy
3. For the measurements of very large distances in
astronomy measurements like meters, kilometers,
etc. are not used.
The Astronomical Unit (A.U.) is a distance
measuring unit, equal to 150 billion meters.
The light year is a measuring unit of distance, not
time: 1 light year = 64,000a.m.
-How many kilometers is 1 A.U.?
-How many kilometers is 1 light year?
