The document summarizes tides, including their causes due to the gravitational interaction between the Earth, Moon and Sun. It describes the stages of a tidal cycle from flood tide to low tide. It distinguishes between spring tides, which occur during full and new moons when gravitational forces align to produce stronger tides, and neap tides during quarter moons when forces are perpendicular and tides are weaker. Rare proxigean spring tides result from a close and aligned positioning of the Moon.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

23. Tidesare periodic rises and falls of large bodies of water. Tides
are caused by the gravitational interaction between the Earth and the Moon.
The gravitational attraction of the moon causes the oceans to bulge out in
the direction of the moon. Another bulge occurs on the opposite side, since
the Earth is also being pulled toward the moon (and away from the water on
the far side). Since the earth is rotating while this is happening, two tides
occur each day.
24. Tide changes proceed via the following stages:
• Sea level rises over several hours, covering the
intertidal zone; flood tide.
• The water rises to its highest level, reaching high
tide.
• Sea level falls over several hours, revealing the
intertidal zone; ebb tide.
• The water stops falling, reaching low tide.
25. Isaac Newton
(1642 -1727) was
the first person to
explain tides
scientifically. His
explanation of the
tides (and many
other phenomena)
was published in
1686, in the
second volume of
the Principia.
Spring tides are especially strong tides (they do not have anything
to do with the season Spring). They occur when the Earth, the Sun, and the Moon
are in a line. The gravitational forces of the Moon and the Sun both contribute to
the tides. Spring tides occur during the full moon and the new moon.
26. Proxigean Spring
Tide is a rare, unusually high
tide. This very high tide occurs
when the moon is both unusually
close to the Earth (at its closest
perigee, called the proxigee) and in
the New Moon phase (when the
Moon is between the Sun and the
Earth). The proxigean spring tide
occurs at most once every 1.5
years.
Neap tides are
especially weak tides. They
occur when the gravitational
forces of the Moon and the
Sun are perpendicular to one
another (with respect to the
Earth). Neap tides occur
during quarter moons.
