Despite the aesthetic differences between these two, their exchange was one of warmth and understanding
This is a new Difference Engine currently under construction at the Science Museum. I should have taken a shot of the information board, but I think this one is destined for a museum in the USA.
Workshop participants learn successful messaging techniques from Paul Andrew and Dave O'Connor in the first session of the day.

This photo was taken October 5th at Clagett Farm in Upper Marlboro, Maryland. This demonstration allows visitors to visualize the difference in runoff and infiltration between permeable pavement, concrete, till non-cover crop, and cover crop. The jars in the back represent infiltration while the jars in the front represent runoff. For the tilled, non-cover crop soil, the runoff is greater than the infiltration. For the cover crop, the infiltration is much greater than the runoff. For the concrete, the runoff is greater than the infiltration. For the permeable pavement, the infiltration is greater than the runoff. This setup demonstrates how different types of soil treatments/urban planning affect sustainability. Tilled soil is generally unsustainable because tilling disrupts soil structure and causes compaction, resulting in decreased infiltration and more runoff. Agricultural runoff negatively affects the environment by carrying with it pollutants such as fertilizer (nutrients), pesticides, and bacteria. Cover crops, however, enhance organic matter and pore space, causing better infiltration and reducing environmental impacts from runoff. Finally, permeable pavement limits flooding from stormwater by allowing infiltration as opposed to concrete.
This photo depicts the ecological concept of human impacts on soil properties and processes. As we discussed in class, urban soils are often highly disturbed due to human activity. This is true for many agricultural soils as well. Specifically, tilling strongly affects the soil profile by disrupting soil structure, leaving soils susceptible to rain and subject to large amounts of soil loss and runoff. Tillage also alters soil structure by diminishing organic matter. We also discussed soil’s numerous physical properties in class. One of these is compaction, which tilling can cause by destroying active organic matter (causing less pore structure created by soil life), and by heavy equipment pushing soil microaggregates together (Hoorman et al., 2011). Finally, we also discussed how soils can develop through losses. Tilled soils are susceptible to nitrate leaching and nutrient loss (Lv et al., 2023).
This photo relates to UN SDG 6-Clean Water and Sanitation. This sustainable development goals aims to ensure access to safe and affordable drinking water and sanitation. Water pollution from agricultural runoff is capable of degrading the quality of drinking water. According to the EPA, pollution from pesticides, fertilizers, and animal manure can enter groundwater and degrade sources of drinking water depending on the local geologic conditions and land use (EPA, 2024). As demonstrated by the image, farmers can take action to reduce their impact on water quality by incorporating reduced till/no-till methods and cover crops to limit runoff. The ecological principle and SDG are closely related. Soil properties and water filtration and efficiency are intertwined. Healthy soil that is strong in structure and high in organic matter has better infiltration and experiences less losses, preventing water contamination and contributing to Target 6.3, which aims to improve water quality by reducing pollution. This also limits pollution to water-related ecosystems, contributing to target 6.6. Practices that enhance organic matter and structure, such as no-till and crop rotation, improve water infiltration and retention, reducing the demand for irrigation and causing increased water efficiency in agriculture.This is critical for target 6.4 which aims to enhance water-use efficiency and “ensure sustainable withdrawals of freshwater to address water scarcity” (United Nations).

Difference between my fiance's choice of marking instruments (left) and mine (right)! I'd rather be taking photos than marking books...
They might look like subtle differences on the outside but not in performance. These are F1 tyres produced by Pirelli. On the left is the red tyre. It is the softest compound and reaches temperature the quickest with the advantage of grip but at a cost of durability. On the right the white tyre which is the hardest compound and offers durability over longer distances. In the middle is the yellow tyre, its compound falls between the other two and it combines speed with durability.
Seen at the F1 exhibition at Excel, London.

Day 2 Monday 8th June
Weather: Mainly clear skies, windless and hot. Ideal!
What a difference a day makes! Our well-situated hotel overlooked the wooded hills of Plitvice National Park, a
UNESCO World Heritage Site. A path to the rear of our hotel led out to an interesting area of trees and a rockstrewn spot sandwiched between farmland, favouring the attentions of the keen dawn patrol. Any hotel boasting
singing Golden Orioles, Black-headed Buntings and Bee-eaters overhead can’t be bad. Among the morning’s
first few butterflies: attractive Pearly Heath and challenging Nickerl’s Fritilllary.
Though not specifically visited for its butterflies, the park’s breathtaking spectacles of dramatic waterfalls and a
series of deep, turquoise-coloured lakes really is a must-see experience. Our woodland walk went beside the
lakes, seeing a few butterflies, birds, dragonflies and a display of Karst-loving wild flowers which was a botanist’s
dream. Eventually reaching the largest lake, we joined a ferryboat which took us to rejoin our minibus.
Unmissable as these truly impressive water features are, it is a major tourist attraction, which is not the usual
Naturetrek scene, and it was time to move on. Several notable species along our leisurely walk were Chequered
Blue, Edible Frog, a sunning Dalmatian Wall Lizard and some Sombre Tits.
Now to concentrate on our key objective…Gerard told us of a “butterfly-filled meadow” he knew and so
following a relatively short drive, we arrived at the southern sector of the National Park and indeed a large,
gloriously grassy basin surrounded by the park’s massive wooded hills. Our first picnic lunch, then into the fray!
Butterflies abounded! A mesmerizing array of families represented and intermingling: the obvious, such as
graceful Back-veined Whites, dramatic Scarce Swallowtail, vivid Southern Festoon, Clouded Apollos and brilliant
orange Purple-edged Coppers as well as perhaps more familiar Small Tortoiseshells and Painted Ladies. Pleasing
were more Amanda’s Blues than anyone in the group had ever seen together before, a Europe-wide declining
species. Small and Chestnut Heaths and Safflower, Grizzled and Oberthur’s Grizzled Skippers threw up
identification challenges. Meanwhile, other blues, browns, yellows and fritillaries demanded our attention. The
drive back to our hotel saw our elated group well rewarded with our action-packed first full day. All kept busily
deployed observing the dramatic scenery and exciting species we had travelled to see.
What a difference a few days can make in the life cycle of a fire. In this particular case, the Thomas Fire that is ongoing in the Ventura County around (and surrounding) in Southern California. The following images were taken by the Terra and Aqua satellites on Dec. 16, 17, and 19, 2017, and during those times fire conditions improved visibly. A difference in winds, in humidity, in the ability of firefighters to control the fire's perimeter, and in the amount of fuel left for the fire to consume can bring a raging fire to heel. This does not mean the fire cannot gain strength again if conditions worsen, but it is heartening to realize that weather conditions can allow firefighters to get a better handle on events as they have in the last few days.
This is a Terra image of the Thomas Fire on Dec. 16, 2017.
